We heard from chris christie, now to another republican who's eyeing on the white house. Some thought that rick perry would never recover from that oops moment. And abc's jeff zeleny went with doing what candidates do, and abc's jeff zeleny went with him. Reporter: I want to show you a copy of this week's cover of "time" magazine. Chris christie had a big win in a blue state, was his win impressive? Yes. Reporter: Is chris christie a true conservative governor? He was a successful governor in new jersey. Now, does that translate to the country? We'll see in later years and months to come. Reporter: Is that code for he's a moderate? No, that's code for truth of the matter, we're all different states. Is a conservative in new jersey a conservative in the rest of the country? Reporter: It sounds like you're skeptical it may not be. I'm just saying that we'll have that discussion at the appropriate time. Okay, some division within the republican party, time for the tea party to be more pragmatic. If you can't win elections you can't govern, the idea that we didn't win in '08 and '12, we're paying a huge price in this country. Criticized for not being a leader in the governing helm is your fellow texan ted cruz. I rise in opposition today to obama care. I enjoyed the 21 hours of his standing up and pointing out the problems with obama care. It would have been wiser for us to have laid the wood to the president, so to speak, of being able to call him out on this and let it become an issue of, mr. President, you own this. This is yours. Reporter: The president has said he's sorry for misleading some of those americans that he thought could keep their insurance plans, do you think that's enough? I don't think that's even close to enough. He needs to stand up in front of the american people. Reporter: Governor perry has just one year left in office, with many wondering, what's next? This was his first trip back to iowa since the 2012 campaign. Meeting with business owners, republican leaders and stopping by a local gun company. Is it too early to ask the 2016 question? It's not too early. Reporter: He knows that if he makes another white house run he'll have to take his famous debate stumble head-on. Commerce and let's see -- i can't -- the third one, I can't, sorry. Oops. Reporter: At a republican fund-raising dinner in des moines, he started his reintroduction like this. Our leaders have forgotten how to governed. And believe me, know a few things about forgetting. Reporter: His new political action committee is launching a new television ad. Pro-growth is putting people to work, something we need more of in washington. Reporter: Making clear he's keeping a door wide open. How tough is it to make a second impression on these republican voters? Well, I think second chance is what america has always been about. Reporter: For "this week", jeff zeleny, des moines, iowa.
