This weekend marks the height of the "celebrity" dog-and-pony shows for the Democrats: Hillary Clinton brought daughter Chelsea (we wondered where she was) and her momma Dorothy Rodham on the campaign trail in Iowa. And Barack Obama brought out the big gun -- Oprah Winfrey -- to Iowa and South Carolina.

But Republicans have friends in Hollywood, too. Mike Huckabee, former governor of Arkansas, also has his own celebrity endorsement: Chuck Norris. Yup. Walker Texas Ranger is backing the conservative candidate. When we first saw the above video, we thought it was a Democratic spoof. But oh no -- the "Chuck Norris doesn't endorse, he tells America how's it going to be" is a genuine -- and funny video -- issued from the Huckabee camp.

Now that got us thinking of other possible celeb endorsements for some of the other candidates:

1. Mitt Romney: He could use a little Donny and/or Marie. They're the best-known Mormons out there, and they're screwed up enough to show us that life isn't all gumdrops and roses for the followers of Joseph Smith.
2. John McCain: Sylvester Stallone is coming back as Rambo, so might as well give a fellow ex-POW a boost.
3. Fred Thompson: Maybe his Law & Order costar owes Thompson a favor?
4. John Edwards: Forrest Gump. Edwards' "aww shucks" persona would fit perfectly with Tom Hanks' country bumpkin.

Got any other suggestions for us?
