Okay, meantime, there is a high-profile political conference in Washington this week. You've got the conservatives all stepping in including Chris Christie coming back in public for a feisty speech. Reporter: Yeah, this is something of a woodstock for conservatives. The biggest gathering we'll see this year of conservatives and potential republican presidential candidates and I'll tell you day one looked a lot like the beginning of a comeback for Chris Chris ki. After a rough couple of months back home in New Jersey, the old Chris Christie seemed to be back. All right. Reporter: Icy and capacityive as ever. What the hell are we paying you for. Reporter: Seen as too moderate. I hope you'll join me. Reporter: -- Wasn't even invited last year but this time received a warm reception and a gathering featuring a who's who of potential republican presidential candidates but this is the crowd for tea partyers like Ted Cruz. His brand of no compromise politics. We need to repeal every single word of obamacare. Reporter: We asked Cruz about that in an exclusive interview for "This week." That's not going to happen while Barack Obama is president, right? Yeah. State the obvious. Look, I will say this. It's unlikely to happen. Unlikely? I'll give you one where it could. Let's say November of 2014 is an election like 2010 which I think we're on the path to be and a tidal wave where republicans don't just win six seats but 10, 11, 12 seat, there's a possibility of that. Reporter: Pretty remote possibility there, George. Cpac continues today. They'll be hearing from Rand Paul, another leading tea partyer and all but certainly presidential candidate. We'll also hear from him on Sunday on "This week." That's right. Talking to all of them. Have a lot more on "This week."
