7) In Wisconsin's Senate contest, Republican Tommy Thompson told the Associated Press that he's raised $2 million since the Aug. primary (after which he's said he was "broke.") No word on his exact haul for the quarter or his remaining cash going into the final stretch. 6) Two new Virginia Senate polls, and one shows a tight race while the other has Tim Kaine up by 7. And new Quinnipiac University/New York Times/CBS News poll shows a neck-and-neck Wisconsin Senate race. 5) The Democratic Senatorial Committee is ad up with a new ad in Connecticut, accusing Linda McMahon of wanting to end Social Security. Meanwhile, the National Republican Senatorial Committee is up with ads in Montana and North Dakota, a spot that ties Democrat Heidi Heitkamp to President Obama. 4) Big day in the Arizona Senate race yesterday, as GOP Rep. Jeff Flake and former U.S. Surgeon General Richard Carmona sat down for their first debate. The Arizona Republic: Flake said in the debate that he wouldn't sign the Grover Norquist anti-tax pledge -- but Norquist's group has him on the list of members of Congress who have already signed it. Meanwhile, Flake's campaign released a poll showing him up 6 and the Democratic Senatorial Campaign Committee released one showing Carmona up 4. Either way, it's a tight race -- a fact that was driven home with a new Flake ad out today, a brutal spot that features Carmona's boss at HHS, who tells the story of "angry pounding" on her door in the middle of the night. "I'm a single mom," she says. "I feared for my kids and for myself. It was Richard Carmona and I was his boss. Carmona is not who he seems. He has issues with anger, with ethics and with women. I have testified to this under oath to Congress. Richard Carmona should never, ever be in the U.S. Senate." 3) Things got heated in Massachusetts when embattled Democratic Rep. John Tierney and GOP challenger Richard Tisei faced off in a debate last night. 2) And Sen. Scott Brown, R-Mass., and his Democratic opponent Elizabeth Warren met for their third debate last night -- the only one in Western Massachusetts Here's the Boston Globe's Glen Johnson: As we noted last night, Warren was more aggressive about tying Brown to the national GOP and Mitt Romney during the debate than she was in the previous two. The two have a final debate scheduled for Oct. 30. 1) And the VP debate is tonight! Here's the New York Times 6 things to watch.
