* For the second time this month, Sen. Pat Roberts' Republican primary challenger, political neophyte Milton Wolf, has picked up an endorsement from a prominent far-right activist group. The Senate Conservatives Fund had already thrown its support to Wolf, and this week, the Madison Project did the same.
* The latest generic-ballot poll from Public Policy Polling shows Democrats leading Republicans by three, 43% to 40%, which is down from the five-point advantage Dems enjoyed in October.
* A new Quinnipiac poll in Pennsylvania confirms what other recent polls have said: Gov. Tom Corbett (R) is in trouble. His approval rating is down to just 36% and a 56% majority believes he does not deserve a second term.
* Rep. Jim Matheson (D) announced he will retire at the end of this Congress, but it now appears he's gearing up for a statewide race, running for either governor or the U.S. Senate.
* In Nebraska, Shane Osborn's Republican campaign for the U.S. Senate is making clear that, if elected, he would support Mitch McConnell for Republican Senate leader. Earlier this week, Osborn, who's already received McConnell's endorsement, dodged a similar question about his intentions.
* And former Montana Gov. Brian Schweitzer (D), apparently eyeing a national campaign in 2016, was in Iowa yesterday speaking to a group of Democrats. The former governor "repeatedly" referenced Hillary Clinton's vote 11 years ago in favor of using force in Iraq.
