Daily Rundown: 8/4/10

CT-Sen: A new Quinnipiac poll finds Linda McMahon (R) closing the gap a bit on Attorney General Richard Blumenthal (D), trailing him by only 10 points, 50% to 40%. Their poll from last month found Blumenthal leading McMahon by 13 points. In the GOP primary (which is on Tuesday), McMahon leads former Rep. Rob Simmons (R) by a healthy 17 points, 47% to 30%. Current rating: Likely Democrat.

FL-Sen: A new poll from McLaughlin & Associates finds Gov. Charlie Crist (I) and Marco Rubio (R) neck-and-neck in the Florida Senate contest. With Jeff Greene (D) as the Democratic nominee, Crist and Rubio are tied at 37%, while Greene picks up 16%. If Rep. Kendrick Meek (D) wins the Democratic nod, Crist narrowly leads Rubio 38% to 36%, while Meek gets 16%.

In other Florida Senate news, Lt. Gov. Jeff Kottkamp (R), who was Crist's running mate in 2006, is backing Rubio for Senate over his boss. That's gotta hurt coming from your second-in-command. Current rating: Toss-Up.

KY-Sen: Lt. Gov. Dan Mongiardo (D), who narrowly lost the Senate Democratic nomination to Attorney General Jack Conway (D), is finally endorsing his formal rival. The more conservative Mongiardo briefly flirted with the idea of backing Rand Paul (R) right after he lost the bitter primary. Current rating: Lean Republican.

OH-Sen: A new Rasmussen poll finds former Rep. Rob Portman (R) leading Lt. Gov. Lee Fisher (D) by four points, 44% to 40%. Two weeks ago, Rasmussen found Portman up by six points. Current rating: Toss-Up.

FL-Gov: A new Rasmussen poll finds a pair of close races for Florida governor no matter who the Republican nominee is. If Rick Scott (R) wins the GOP nod, as is expected, he leads state CFO Alex Sink (D) and Bud Chiles (I) 35-31-16. With Attorney General Bill McCollum (R) as the GOP nominee, Sink leads 31-27-20.

MD-Gov: Sarah Palin endorsed energy executive Brian Murphy's (R) underdog bid for governor, passing over likely GOP nominee former Gov. Bob Ehrlich (R). But instead of wallowing, Ehrlich is trying to use this non-endorsement to his advantage, trying to boost his moderate credentials in this dark blue state. Current rating: Toss-Up.

MI-01: Only one vote now separates surgeon Dan Benishek (R) and state Sen. Jason Allen (R) from yesterday's GOP primary, with the ever so slight advantage going to Benishek according to the Michigan secretary of state's office. The recount is expected to take at least two weeks, but probably longer. And while Benishek and Allen worry about recount lawyers and fees, Democratic nominee Gary McDowell (D) will get quite the head start going into the general election. Current rating: Toss-Up.

PA-07: Pennsylvania Democrats helped gather enough signatures to get tea party activist and and "birther" Jim Schneller on the ballot in Pennsylvania's 7th district. His candidacy should siphon off votes from former U.S. Attorney Pat Meehan (R)--the GOP nominee--on his right, thereby helping state Rep. Bryan Lentz (D) in a race where every vote counts. The question is: how much of a role did the Lentz campaign have in this? Expect Meehan's people to make some noise about this. Current rating: Toss-Up.
