Is the Tennessee Senate race really over? The newest polls show the race evening out, and the behavior of the parties themselves show continuing suspense about it. Going into the home stretch of a campaign, you can tell a lot about the parties' priorities by where they send their big guns. Yesterday, both Corker and Ford held rallies featuring some considerable starpower: Bob Corker's rally featured John McCain, while Harold Ford Jr. brought in Barack Obama. So apparently the Dems think an appearance by Obama could potentially fire up supporters to win the race, while the Corker campaign felt the need to bring in McCain to secure their current lead.
