While the conference can often give a boost to candidates, it has also been the venue for one prominent exit from the Republican primary: It was at CPAC four years ago that former Massachusetts governor Mitt Romney (R) announced his exit from the GOP presidential race – a move that stunned many of the activists and reporters who were in the room.

Palin is not taking part in the presidential race this time around and said Wednesday night that she has not yet settled on a candidate in the field. But her planned CPAC address – as well as a series of TV appearances in recent days and a Washington Post op-ed last weekend – would suggest that she is keen on being part of the conversation.

Also among those speaking at this year’s CPAC will be former Massachusetts governor Mitt Romney, former House speaker Newt Gingrich (Ga.) and former senator Rick Santorum (Pa.).
