On day one of the rio olympics, fresh security scares. A stray bullet ripping into the media tent of the dressage equestrian event. Rio 2016 officials said that the event wasnt the target, but it was only the start. As the games began, it seems the lines never ended. Spectators bunching in the heat. Lines stretching nearly a mile. And magnetometers not working. And then, at the road cycling event, the bomb squad rushing in for what turned out to be an unclaimed bag. Rios bomb squad took us deep inside their operations. Of exactly how to use how to use the robots to conduct the remote detonations. Wow. Theyre up against this. Confiscated by drug lords.

Reporter as for the untold areas nells of these weapons still in the hands of the socalled bad guys, keeping them out of the olympic zone is a grueling job, often conducted in the bomb suit. Oh, my gosh. Just getting it on is a threeperson job. So, how many hours would you have to spend in this suit . Depends the driver. Reporter now, Security Officials here tell us that theyre not so worried about the criminal gangs in this city. But theyre concerned about a possible lone wolf attack, amy. All right. And matt, i have to ask you. You and i both know its been very hot here the last few days. Near 90. What was it like in that suit . Reporter it was hot. And it was stinky.

A brandnew abc news Washington Post poll Shows Hillary clinton leading donald trump by eight points. Shes making gains among women and consolidating her support within her own party. Meanwhile, trump trying to put a tough week behind him with a new line of attack against clinton. Abcs devin dwyer is out on the trail, in manchester, new hampshire, this morning. Hey, devin, good morning to you. Reporter good morning, dan. Donald trump is down in our new poll in part because of concerns about his temperament. Overnight here, trump turning the tables on clinton, suggesting shes losing her mind. Overnight, in new hampshire, donald trump recalling his first big political victory. The last time i was here we won. Right . We won. Big league. Reporter in attacking his democratic opponent, who he trails by eight points in a new abc news poll. Unstable. Hillary clinton. And you saw that, did you saw that where she basically shortcircuited . Reporter trump is zeroing in on clintons explanation for why she twice wrongly implied that the fbi director said she had been truthful with the American Public about her email. I may have shortcircuited it and for that, i will try to clarify. Because i think, you know, Chris Wallace and i were probably talking past each other. She used the term short circuited. The people of this country dont want somebody thats going to short circuit up here. Okay. Reporter trump trying to turn the page on a week of distraction, controversy, and sliding poll numbers. Though his supporters are unfazed. Who cares about polls . Donald trump is the man. He knows what hes doing. Reporter and the new abc news poll shows clinton consolidating support among women. Hitting her highest level of support yet. It also found strong disapproval of trump for his handling of those muslim parents of a fallen american soldier. Including disapproval from a majority of republicans. Dan and paula . All right, devin, we want to thank you. To get more on these latest polls, as well as voter sentiment, lets bring in martha raddatz. Gearing up to host this week. Thank you for joining us. Good morning. Good morning. If you dig into this poll, there are worrying numbers here for donald trump. 79 of americans say he doesnt show enough respect for people he disagrees with. 70 express anxiety about a trump presidency. And 67 think he lacks the personality and temperament to serve effectively. In sum, how bad is this for the campaign . There is reason for deep concern and hope in the numbers for the trump campaign. Concern because as you said, a majority of Americans Still think trump is essentially unqualified to be president. And that number hasnt budged in the last year. And that is exactly the message the clinton camp will hammer into the electorate. But it isnt over yet. Not in august. Things could even out after clinton sees her convention bounce deflate. If trump can stay on message, he could reduce some of the hesitation. Dan and paula . Yeah, we got a couple of months left. I know you just spent a lot of time in pennsylvania. Its a battleground state. It hasnt swung republican since i believe 1988. What are voters there saying . Well, this is a mustwin state for trump. And voters there are split among the same geographic, racial, lines as elsewhere. In western pennsylvania where manufacturing and mining jobs have all but disappeared. Poor, less educated white voters are turning to trump. They like his message, his brashness. They dont trust Hillary Clinton. But the same comments that excite them are turning off educated white and minority voters in philadelphia and its suburbs. If that trend continues it does not bode well for mr. Trump, guys. Yeah, a lot of polarization there. We want to thank you, martha. We know you have a big show to prepare for. Go do that. A reminder, everyone, watch martha and our Powerhouse Political Team covering all angles. Trump adviser Rudy Giuliani will be on the show. Be sure to catch this week right here later this morning.
