The Conservative Political Action Conference is entering its 40th year of bringing big names together to talk conservative issues.

The event, which takes place at National Harbor near Washington, D.C., is a project of the American Conservative Union. Speakers this year include Sarah Palin, Mitt Romney, Paul Ryan and Marco Rubio.

Below, a liveblog of the latest updates from CPAC:

HuffPost's Jason Linkins reports:

Wisconsin Gov. Scott Walker took the stage Saturday at CPAC, praising the assemblage for its support during the fraught Wisconsin recall fight, which Walker won, allowing him to stay in power. His speech was themed around the idea that the states are the laboratories of policy -- "Real reform does not happen in Washington, it happens in the statehouses throughout this country," he said -- and that he, in particular, was leading the way to end "government dependency."

If future GOP presidential runs depend on silver-tongues articulation of dorm-room "makers vs. takers" arguments, then Walker's future is pretty bright.
