If Mississippi Gov. Haley Barbour (R) runs for president, he'll have the support of at least one Republican member of Congress.

Rep. Gregg Harper (R-Miss.) was so impressed by Barbour's "State of the State" address on Tuesday night he said he hopes the two-term governor will run for president.

Harper, who was in the audience for the speech, according to Mississippi Public Broadcasting, said on Twitter:

I hope @HaleyBarbour will run for president. Great speech at the State of the State.

Few Republican members of Congress have been willing so far to declare their preferences for Republican candidates for president, especially with a full year before the primary contests begin in earnest.

Rep. Pete King (R-N.Y.) has said New Jersey Gov. Chris Christie would give Republicans the best shot of beating President Obama in 2012; Rep. Charlie Dent (R-Pa.) also said Christie would be an "outstanding presidential candidate."

Christie has denied interest in running for president, but was one of three Republican governors considered possible contenders to deliver their "State of the State" speech on Tuesday. In addition to Christie and Barbour, Indiana Gov. Mitch Daniels (R) also delivered his highly anticipated address. 

Barbour, the chairman of the Republican Governors Association (RGA) for the 2010 cycle, said he has no timeline on deciding whether to run. Daniels has also downplayed somewhat the chances that he'll run.

The speeches are opportunities to highlight accomplishments they've made as governor, particularly some steps they've taken that could appeal to Republican primary voters in 2012.
