WHAT YOU MIGHT HAVE MISSED:
* The Michigan state House passed two "right to work" bills Tuesday, leaving them for Gov. Rick Snyder (R) to sign. Meanwhile, protests in Lansing continue, and former congressman Mark Schauer (D-Mich.) was on the wrong end of some pepper spray.
* As the "fiscal cliff" negotiations continue, the conservative group Crossroads GPS is spending $240,000 on radio spots targeting five potentially vulnerable Democratic senators up for reelection in 2014: Sens. Mark Begich (Alaska), Mary Landrieu (La.), Kay Hagan (N.C.), Tim Johnson (S.D.) and Jay Rockefeller (W.Va.) (though the Rockefeller ad directs listeners to call recently reelected Democratic Sen. Joe Manchin). The ads blast Obama's "fiscal cliff" pitch and call on the Democrats to support a "balanced plan."
* Senate Majority Leader Harry Reid (D-Nev.) said Tuesday that it will be “extremely difficult” to get a deal done to avert the fiscal cliff before Christmas. Meanwhile, House Speaker John Boehner (R-Ohio) and Senate Minority Leader Mitch McConnell (R-Ky.) each underscored the importance of Obama offering satisfactory spending cuts as part of any deal.
* Boehner has sent another "fiscal cliff" offer to the White House, but his office is declining to outline the specifics of the proposal.
WHAT YOU SHOULDN'T MISS:
* New Jersey Gov. Chris Christie (R) got his first Democratic challenger on Tuesday when state Sen. Barbara Buono (D) filed paperwork for a bid. Buono would face an uphill climb against Christie, as recent polling shows her trailing the governor by 35-40 points. Newark Mayor Cory Booker (D), who would be the most formidable Democratic challenger to Christie, said he will likely decide in the next two weeks whether he will run.
* McConnell is in rough shape for his 2014 reelection bid, though he still leads all comers, according to a new poll from Democratic automated pollster Public Policy Polling. The poll shows McConnell's approval rating is 37 percent, compared to 55 percent disapproval. Still, he leads 2010 Senate candidate Jack Conway, actress Ashley Judd, Lt. Gov. Jerry Abramson and Secretary of State Alison Lundergan Grimes all by at least four points and takes between 47 and 48 percent of the vote in each matchup.
* PPP also shows South Carolina Gov. Nikki Haley (R) in a virtual tie with 2010 opponent Vincent Sheheen, with Sheheen at 46 percent and Haley at 44 percent. But neither Haley nor Sen. Lindsey Graham (R-S.C.) appears overly vulnerable to a primary challenge (both are considered potential intra-party targets).
* The Koch brothers have postponed their semi-annual meeting, which was set for next month. Charles Koch told supporters the meeting was being postponed until April because the group needed more time to gather and digest the data from the 2012 election.
* Sen. Kelly Ayotte's (R-N.H.) eight-year-old daughter doesn't want her to run for president.
