Tom Tancredo is back on the road. Today he's speaking in South Carolina.

It's the third early presidential primary state Tancredo has visited this year, as he toys with the idea of a 2008 race.

He's a one-issue politician, though, limiting his talks to immigration reform. He also limits his talks to audiences most likely to agree with him.

Tancredo was scheduled to speak today night before hundreds of members of the Fraternal Order of Police at a hall outside Charleston.

Any guesses as to when his constituents will start asking, "Congressman, what have you done for us lately -- other than embarass us?"
