Hurtling Toward 2010, 10/15

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

Senate Majority Leader Harry Reid (D-NV) will start airing TV ads in his home state tomorrow; Rep. Roy Blunt (R-MO) is outraising Missouri Secretary of State Robin Carnahan in that state's Senate race; Rep. Mike Castle (D-DE) and Delaware Attorney general Beau Biden (D) are in a statistical dead heat for Vice President Joe Biden's former Senate seat; as polling in Pennsylvania's Senate race continues to vary, Rasmussen shows Sen. Arlen Specter (D) trailing both GOP challenger Pat Toomey and his primary opponent, Rep. Joe Sestak (D); meanwhile, Siena shows Democrat Bill Owens leading in New York's 23rd district.
