Washington (CNN) -- Potential Republican presidential candidates Mitt Romney, Sen. John Thune, Tim Pawlenty and Rep. Ron Paul all get their chance Friday to address the annual Conservative Political Action Conference -- a gathering of more than 10,000 GOP activists from across the country.
The list of speakers for the three-day meeting is a virtual "Who's Who" of GOP presidential politics.
Romney, the former Massachusetts governor, and Pawlenty, Minnesota's former governor, are considered likely to vie for the 2012 Republican nomination. Paul is considering another run after his failed 2008 bid and Thune of South Dakota is a relative newcomer to the presidential discussion.
Romney may find himself in the spotlight as observers watch for a potential defense of what has been dubbed "Romneycare" -- a health care overhaul he supported as governor of Massachusetts. CNN
