The u. S. Primary season takes place on thursday. And the lineup of republican contenders taking part has now been announced. Fox news used an average of five National Polls to determine the top ten candidates. And theyll face each other in a primetime broadcast. The other seven candidates will appear in a separate earlier forum. Not primetime. Dana bash reports theyll all try to stake out their own positions, grab some of the attention and the spotlight from the frontrunner, donald trump. Reporter in New Hampshire this sneak preview of sorts of what the crowded Republican Debate stage will look like. With one glaring exception. Donald trump, who is now leading the gop president ial pack in multiple polls by double digits. Ive had Great Success. And they, you know, just and people see that. And i would put all of that energy and whatever that brain power is, whatever that type of brain into making our country so donald reporter tonight the key question ahead of the first president ial debate thursday is how everyone else will navigate the trump dynamic. Sources close to Wisconsin Governor Scott Walker say he plans to pivot as much as possible to his own record of fighting for conservative principles. What will make the difference in how we win the nomination is people realize they dont just want a fighter, they want someone who can fight and win. Reporter jeb bush was asked if he ever imagined being in a debate with a reality tv star. When i was growing up we didnt have reality tv either. Okay. Reporter then theres Ohio Governor john kasichs unorthodox approach. Maybe ill give him a hug. I dont know. Reporter kasich may have only gotten into the race two weeks ago, but it was announced tonight he will edge out the candidate who has been itching to go head to head with trump, former Texas Governor rick perry. Donald trumps candidacy is a cancer on conservatism. Reporter though there are 17 gop candidates, debate rules say only the ten with the highest National Poll numbers will be on the stage together. It puts trump on the main stage with former governor jeb bush, Governor Scott walker, former governor mike huckabee, neurosurgeon ben carson, along with senators ted cruz, marco rubio, and rand paul. And governors Chris Christie and john kasich. That leaves seven other candidates hunting for attention in other ways. Lindsey graham found creative ways to destroy his cell phone after trump famously gave out his number on live tv. I dont know if its the right number. Lets try it. 202 reporter on that note trump got a taste of his own medicine. The website gawker published one of the billionaires numbers, and trump quickly changed the voicemail. Hi. This is donald trump, and im running for the presidency of the United States of america. Reporter and even those in the top ten are looking for buzz. Ted cruz cooked bacon by heating up his weapon. Machine gun bacon. Reporter a top aide to one of the ten candidates who will be on the main debate stage said something very wise to me, and that is historically you dont win one of these early zabdebat but you sure can lose. And thats the driving force behind a lot of these candidate debate prep sessions, do no harm. Dana bash, cnn, washington. For the past few weeks donald trump has called his opponents losers, dummies, and stiffs. Theyve called him a jackass, a cancer, likened him to a drunk driver at a nascar race, and a rattlesnake with a toothache. But american voters, at least in the past, have expected a higher standard of behavior during president ial debates. And that could be the biggest challenge of all for mr. Trump. For more, jeffrey lord joins us now from harrisburg, pennsylvania. Hes a former political director for the reagan administration. And hes the contributing editor to american spectator. Jeffrey, here we go again. Do you think if most people by the end of that darkts if they could picture donald trump in the oval office if he gets into specifics, not just one liners, he walks await big winner and if he cant then in his words hes the loser. Well, heres the problem with specifics, john. Because there are ten of them on the stage, no one is going to have much time to get into specifics. And to be perfectly candid, that is probably going to suit Donald Trumps style just perfectly because it will give him enough time to get out his message, which you know, in a reagan fashion he just repeats over and over and over again. But there isnt going to be time to say, you know, the Second Chapter of the third verse of the air force budget says we need to do the following 17 things. So hell probably just repeat his message, just be him. The other guys are going to be the ones that have the problems. If they want to display their policy chops they are going to have a hard time because of the constraints. How do they get under his skin . His support in the past for Hillary Clinton . Main his questionable business dealings . Whats the Silver Bullet here . You know, in truth im not sure that there is one here. I just think theyve got to be themselves with this and he will be himself. Everybody is tuning in to see what he will do. I think hes just going to be you know, today let me give you an example. He put out a facebook post. Remember, this debate is cosponsored with facebook. And its just a short video that challenges his opponents. He says Something Like theyre not good negotiators. So i want to ask them, what would you do to make America Great again . And i saw this. And i thought, you know, this is the apprentice. This is the presidency as the apprentice. And these candidates are now being, you know, asked to answer his questions. So already, you know, hes sort of got them where he wants them, if you will. And im sure he will repeat this again. Well, thats yeah, this is the reality tv version of all of this. Politics was reality tv long before reality tv. Donald trump, you know, was the star of the apprentice. And so this really does give him such a huge advantage. Absolutely. I mean, not for nothing. I mean, Ronald Reagan was a longtime both movie actor and a Serious Television actor. And it did get him an advantage. Theres no question. Toward the very end of his term i think it was tom brokaw that asked him about his acting background and his experience, and he said his answer was something to the effect i dont know how i could have done the presidency if i didnt have my acting skills. And i think we are going to see some of that in play. Some of these folks, theyre all good folks but make no mistake, theyre policy wonks. Theyre going to stumble and you know, i fear for them in some ways. Well, then if youre donald trump, who do you go after . Do you try and knock down jeb bush or scott walker . Whos the main target . You know, i think he will go after jeb bush in some sense or maybe the bushes plural, and its entirely conceivable to me that he would want to draw the sort of reaganbush divide, if you will, which is basically the republican you know, the conservative versus the moderates fight thats been going on for decades and decades and decades. And personalize it with the bushes and talk about it in that sense and then see if he can apply some version of that to the others. Whatever happens, its going to be interesting to say the least. Jeffrey lord buy popcorn bags, without doubt. It will be good tv. Were looking forward to it. Good to speak with you as always. Thanks, jeffrey. Thanks, john. And jeb bush stepped into a controversy over funding planned parenthood, and there was a swift and blunt reaction from democrat Hillary Clinton. Well have more on mr. Bushs efforts to clarify his position later this hour. In the meantime, we go to india where heavy rain and floods are affecting an estimated 10 Million People.

The rocky fire in the northwest is the largest and has burned 67,000 acres, more than 27,000 hectares. At last report it was 20 contained. And as the flames spread, thousands are being evacuated from their homes. Late details now from cnns paul verkammen. Reporter at the rocky fire in Colusa County a test of wills. A stubborn fire pushed at times by erratic winds versus many selfreliant rural people who live here because there are fewer folks around to tell them what to do. Wills were tested when word came for about 13,000 of them to evacuate as the rocky fire exploded. When you start seeing smoke plumes come up that are severe, black, you know theyre in the brush, and theyre not thatfor away. This is a problem, you look at it, hey, its time to go. And when you see flames. When you see flames, its really time to leave. Reporter so just where did joe welz, resident of this back country for 27 years, go . The moogs lodge. Thats right, moose lodge. Often a hub for bingo and karaoke and now a haven to ride out a fire thats burned more than 65,000 acres. Lodge volunteers say 200 to 300 people sheltered here overnight. Donated food is piled up on tables. Free pie and french toast. Its not part of red cross. Nothing government. This is all community here. This is a community at its finest. Reporter rie hannon garcia and her displaced visitors hang on weather reports. You can take a breath. Right now when i woke up this morning and i saw it hadnt grown, everybody was safe, it was like, whew, finally. We need a break. They need a break and we need a break. Reporter a break because the rocky fire is unpredictable. Jumping highway 20 late monday and messing up any thoughts of leaving the moose lodge for home. More food arrived. I asked for a little help. Look at this room. This communitys come together. Its beautiful. Reporter in a wicked fire a bingo hall can look like the taj mahal. The weather took a turn for the better in fireravaged northern california. Especially here on the rocky fire in Colusa County. Other news where in modo county thats where david rule from the Black Hills National Forest was scouting a fire last week when he perished. An autopsy has revealed that he died of Carbon Monoxide poisoning and smoke inhalation. Now, on the rocky fire, very little activity for firefighters in terms of an intense firefight. They were basically just continuing to watch the perimeter of this blaze and perhaps an omen from Mother Nature. You could see some tulle elk grazing, looking for food between the burn areas. Reporting from Colusa County im paul vercammen. Back to you. Meteorologist ivan cabrera joins us now. Everyone looking to the forecast wanting to know if conditions are going to ease up, what the future holds at least over the next couple days. Over the next few days i think we may even get a couple of showers out there but just crossing our fingers here at this point. This is the dry season there. So to get any rain in california this time of year would be something. But what we dont want is the temperatures he to go higher than they have been 37 weve seen tripledigit heat there. At least were doing a little better. Lets recap here what we already know now, including three counties there in california. 67,000 acres. Containment is higher. But the structures that are being threatened actually going up. So were approaching now 7,000 structures threatened and we have a lot of people displaced. Firefighting efforts will continue as far as the weather well get to that in a second. Look at this now. 67,000 acres. Were talk an area now that has burned that is larger than the square mileage of sacramento. That is just incredible there. We started with just a couple hundred acres. Just a few days ago it seems. Temperatures climbing up by the afternoon well get into the mid 80s to approaching 90 degrees. Once that happens of course relative humidity goes down and so do the winds begin to climb up through the afternoon. So we have some gusty winds. This is not good. Low 90s wednesday and heading into thursday. Well have warm temperatures. Now, by friday what youre seeing here, upper 80s, that is a disturbance thats going to try, john, to move in from the pacific here. And this is an upper low, and its going to move in. So by the time we get into friday, maybe a couple of showers out of that. But at least what that will do even if we dont get showers, it will cool off the temperatures a little bit. So well go from the 90s to 80s and thats a little bit of help and well take what we can get at this point. You dont sound very optimistic on that. Well, im not. Some of the models just arent getting anything out of it. And in fact if we get some thunderstorms you know that could cause some additional fires with lightning. Okay.

The pentagon now scrambling to figure out what to do next. Theres no military logic for putting that small a force in the field. One, theyre incredibly vulnerable. And two, theyre certainly not going to attack anybody with just 40 or 50 peop
