Virginia’s Republican Senator John Warner will not seek re-election. Senate 2008 Guru notes what we can likely expect in the race:

John Warner just announced that he will retire at the end of his current term, rather than seek re-election in 2008. Expectations are the following: for the Democrats, popular former Governor Mark Warner, who left office with an approval rating exceeding 80%, will enter the Senate race; for the Republicans, we may see a bloody primary battle between Rep. Tom Davis and former Gov. Jim Gilmore.
