GOP preaches to the base at CPAC: "I don't see this great divide," Ryan says

Where did the Republican party gone wrong?

A lot of different theories from a lot of big name Republicans at the Conservative Political Action Conference or CPAC - the largest annual gathering of conservative leaders and activists.

Here are a few:

"We have to stop letting the media define who we are and what we stand for," Gov. Chris Christie (R-NJ) said.

"Conservatives can't afford or expect to win elections by default. We need to win elections with a mandate," Sen. Mike Lee (R-TX) said.

"We put our head down, we stood for nothing and we got walloped." Sen. Ted Cruz (R-TX) said.

"The way the left tells it, the Republican Party's in this big massive civil war. It's Tea Party versus establishment versus libertarians vs social conservatives. There's infighting, conflict, backbiting, discord. Look, I'm Irish. That's my idea of a family reunion. I don't see this great divide in our party. What I see is a vibrant debate," Paul Ryan said.
