Hurtling Toward 2010, 12/2

The 2010 midterms are just around the corner (sort of). Here's what's happening:

Prominent Blue Dog Rep. John Tanner (D-TN) will retire at the end of his term, giving Republicans a chance for a pickup; former McCain organizer Lang Sias will announce his challenge to sophomore Rep. Ed Perlmutter (D-CO) tomorrow; former Chicago Inspector General David Hoffman (D) is running a TV ad in the race for President Obama's old Senate seat; former U.S. ambassador to Ireland Tom Foley (R) is expected to drop his bid to challenge Sen. Chris Dodd (D-CT); a Public Policy Polling survey shows Wisconsin's gubernatorial race to be a tossup, with Democrat Tom Barrett holding a slim lead; and Rep. Michael Capuano (D-MA) is trying to make a last-minute surge against leader Martha Coakley (D) in the race for the late Sen. Ted Kennedy's old seat, with endorsements from former Gov. Michael Dukakis, Rep. Edward Markey (D-MA), and The Boston Herald.
