Rep. Tom Davis appears to be running for the GOP’s Senate nomination in Virginia. On the plus side: He’s very smart, he’s a political maven among political mavens, and he’ll work very hard. He won’t have a “fire in the belly” problem. On the minus side: He’ll be an underdog against Democrat Mark Warner, conservatives don’t trust him and will look for an alternative candidate, and his Senate candidacy very possibly will cost Republicans the House seat that Davis currently holds–his moderate Republicanism is a good match for the district, which is trending Democrat. Another GOP candidate won’t fare as well as Davis has.
