Sunday show preview: A 2012 candidate review and talk about money matters

As the race for the 2012 Republican presidential nomination begins in earnest, candidates and possible candidates are beginning to dominate the guest list for the Sunday morning talk shows.

This weekend "Fox News Sunday" has two top-tier Republicans scheduled to appear. Rep. Ron Paul (Texas) is already declared himself a candidate. Former Gov. Mike Huckabee (Ark.) is making an announcement Saturday about his future, but he leads many polls of potential candidates.

On NBC's "Meet the Press," former House Speaker Newt Gingrich (R-Ga.) will be the guest. Gingrich announced his candidacy earlier in the week.

Gov. Nikki Haley (R-S.C.) is on ABC's "This Week." She's not running for president in 2012, but some have floated the idea that she would make a good running mate for the Republican nominee, and her state's primary could be the deciding factor in the primary.

CBS' "Face the Nation" will focus on policy over politics.
