Time Magazine offers its list of the "Top Ten '08 Senate Races to Watch" - nine of the ten are Republican-held seats.
Nebraska: Former Senator Bob Kerrey announced this morning that he will not run for the Senate in 2008 after all. At least we finally know. Paging Mayor Fahey!
Virginia: Everyone and their mother at this point are reporting that GOP Rep. Tom Davis won't run for Senate in 2008. He is scheduled to make an announcement tomorrow regarding his political plans. Hopefully he'll retire from the House, too, and open up that competitive seat. This would leave failed former Gov. Jim Gilmore with a direct shot at the GOP nomination, while the latest polling has him losing to popular former Governor Mark Warner in a general election by a mere thirty points.
Texas: With Mikal Watts' departure from the Senate primary, State Representative and Lieutenant Colonel Rick Noriega will have the field to himself to get press and define himself and his campaign while building the bankroll to run competitively.
North Carolina: The first polling is out matching Democrat Jim Neal against absentee Republican Elizabeth Dole, with Public Policy Polling giving Dole a 47-32 edge. Given how little name ID Neal must have to start, a fifteen-point deficit is hardly a terrible starting point. And, again, Dole can't break 50% against anybody. PPP pegs Dole's approve-disapprove at a dismal 44-41. Meanwhile, rumor has it that State Senator Kay Hagan is reconsidering a bid and is in touch with national Democrats.
Montana: If Montana Republicans get more desperate, I suppose they can turn to this guy.
