Democratic side. Bernie sanders joins us live as he takes the edge in iowa and new hampshire. Can he pull off an amazing upset . Plus the powerhouse roundtable breaks down the gop crisis and what sara palin, glenn beck and this weeks big endorsements will mean for the race. Announcer and later, the powerhouse puzzler brought to you by voya financial. Im val, the orange money retirement squirrel from voya. Val from voya . Yeah, val from voya. Quick question, what are voya retirement squirrels doing in my house . Were putting away acorns. You know, to show the importance of saving for the future. So youre sort of like a Spokes Person . No, im more like a metaphor. Okay, a spokesmetaphor. No, im. Youre a spokesmetaphor. Yeah. Ok. Janet . Cough if you can hear me. Dont even think about it. I took mucinex dm for my phlegmy cough. Yeah. But what about mike . It works on his cough too. Cough it works on his cough too. Mucinex dm relieves wet and dry coughs for 12 hours. Ve. How about that support they got. Glenn beck friday. Donald trump endorsed by sarah palin. What will these endorsements do whether its donald trump or ted cruz, i dont think the endorsements mean much. For ted cruz, his support comes much more from tea partytype folks, folks who get concerned about the things that jeb bush brought up earlier today. Trumps support comes from the populous wing of the party. Theres this big divide on the right. Mike, very quickly, 20 second and jeb bush keeps saying hes not a true conservative. But the consecutives dont care. Donald trump has managed to galvanize an entire range of people outside of the republican party. Way to stay inside time. Back in a moment with bob its called an alive day, and this week our abc colleagues and friends, correspondent bob woodruff and cameraman will celebrate their tenth alive day. Hard to believe that it was ten years ago, that bob and david were badly injured by a roadside bomb in iraq. Morning after somewhat encouraging calls, i got a call just as i was heading into the building to join george on this program to deliver the news of the bombing. Good morning, everyone. We have to begin today with some news that has hit close to home at abc news. Bob woodruff and his cameraman were reporting today in iraq when their convoy was hit by an i. E. D. They were in a convoy with u. S. Military from the 4th infantry division. The i. E. D. Went off. Both immediately injured. Both have injuries to the head. We delivered just the facts. But at that moment n a small combat hospital so far away, military surgeons were removing part of bobs skull to relieve the pressure on his brain. Once stabilize both bob and doug would begin the journey thousands and thousands of our Wounded Service members have germany, then finally to Bethesda Medical Center here at home. For nearly 40 days bob lay in a coma, his wife lee, their four children and extended family at his side. Then slowly and miraculously he is one special guy. After multiple surgeries to rebuild his skull, an intense cognitive surgery. Bob was well on his way to recovery. Good evening. Im bob woodruff. Remarkably just over a year later, bob was back on the air. And since has spent the last decade reporting from a around the globe, from inside north korea. Were told that 10,000 to 15,000 have actually come here. To deep down a colombian mine. Thats the most frightened i have been. But through it all, bob had never forgot what the military who treated him like one of their own. Lives to helping our wounded support them. The bob woodruff foundation, with its annual stand up to heroes gala in new york, has raised more than 30 million. Reaching more than 2 million of our veterans and families. And im proud to be part of that organization and proud that bobd woodruff joins me now from his latest assignment, beijing, where he began his career. Happy alive day, my friend a continues to shoot beautiful video for abc. Bob, i want your thoughts on this anniversary . Well, you know, its been its hard to believe its been ten years. Time has flown past so quickly, so quickly i mean, we i got so many friends, i talked to my other teammates to celebrate and i think we just feel just so lucky really to be here at all and to be here, martha, you have been such a huge supporter from the beginning. All of us love you. Lets talk about those wounded veterans that you have helped. Its remarkable how much you and lee have done and what thats meant for you and your own recovery. You know, i think ill never forget that story. I was in a coma for five weeks as you know, and my wife told me later on, on that same floor, there was an another marine that while we were surrounded by our family and friends, but there was no family members or friends surrounding him and she said to herself and my brothers as well, they said, when were done with this, lets do something so it doesnt happen. All of our medical care was the same. But in terms of how to deal when they go back to their communities, they fit in again and they do that transition well, we got to do some organization. Martha, as you also know, this is probably the most fulfilling i have ever done in my life. The most fulfilling for me. Bob woodruff, thank you very much for joining us, my friend, this morning. Thats all for us today. Thanks for sharing part of your sunday with us. Check out world news tonight and well see you back here next
