* In Maine's gubernatorial race, PPP shows Rep. Mike Michaud (D) leading Gov. Paul LePage (R) by just two points, 38% to 36%, because Eliot Cutler (I) continues to split the mainstream vote, garnering 15% in the poll. In a head-to-head match-up, Michaud's advantage grows to 14 points.

* In North Carolina, Sen. Kay Hagan (D) is still leading her Republican rivals in the latest PPP poll, but her margin has shrunk in a hurry. While Hagan enjoyed double-digit leads in September, her advantage is just two or three points now against her various Republican challengers.
* Rep. Phil Gingrey (R), one of several House Republicans running for the Senate in Georgia, has a new ad vowing that he'll "repeal Obamacare" in his first term or he won't seek re-election.

* The Republican field of Senate candidates in Iowa got a little bigger yesterday, with businessman Mark Jacobs entering the race -- the seventh GOP candidate to launch a campaign. The winner will likely take on Rep. Bruce Braley (D) in 2014.
* And in Michigan, conservative business leaders are reportedly "plotting to take down" Rep. Justin Amash (R) next year. Amash is facing challenger Brian Ellis in a Republican primary.
