The annual Conservative Political Action Conference, more commonly known by its acronym CPAC, has always attracted an interesting array of pop culture types.

Last year's CPAC included actor Richard Dreyfuss, who walked around D.C.'s Marriott Wardman Park Hotel spewing rhetoric about civics and civility in politics, and politician Jimmy McMillan, who tried to get young conservatives interested in his "Rent it Too Damn High" party.

This year, actor Stephen Baldwin has promised to make a return appearance. Baldwin missed the conference last year, but was in charge of "XPAC" the year before, an area where younger attendees could play video games and hang out.

Also on the roster is Kirk Cameron. Yes, the Kirk Cameron, veteran of the show "Growing Pains." Cameron is coming to the three-day affair to talk about his documentary, "Monumental: In Search of America's National Treasure."

Finally the Duggar family's matriarch Michelle Duggar will be on hand Friday to sign copies of her book "A Love that Multiplies." No word yet on whether Jim Bob and the 19 kids will be in tow, but on past trips they've requested six adjoining rooms for their stay in the District and arrived in a bus that takes up five parking spots.
