* The Koch brothers' Americans for Prosperity is launching another round of anti-healthcare attack ads, this time targeting Democratic Sens. Kay Hagan of North Carolina, Mary Landrieu of Louisiana, and Jeanne Shaheen of New Hampshire. AFP will spent more than $2.5 million to run the spots over the next three weeks.
* Sen. Mark Begich (D) continues to hit the radio airwaves as part of his re-election bid, launching a new ad today "touting his work to expand drilling and mining in the Arctic."
* Louisiana's U.S. Senate race got a little more interesting this week with state Rep. Paul Hollis (R) throwing his hat in the ring. Most of the state GOP has rallied behind U.S. Rep. Bill Cassidy (R), but Hollis says the congressman hasn't generated "excitement" from the base.
* Ohio's gubernatorial race also got a little more crowded this week with County Commissioner Todd Portune announcing he'll take on Ed Fitzgerald in the Democratic primary.
* In Hawaii, the primary fight pitting appointed Sen. Brian Schatz (D) and Rep. Colleen Hanabusa (D) has very little to do with issues and/or ideology. Rather, "the divide is personal."
* The Democratic National Committee relied on Republicans' presidential impeachment threats in a year-end fundraiser.
* Rep. Ed Royce (R) accidentally filed a statement of candidacy for his re-election bid for the wrong district. An aide to the congressman blamed a typo.
* Speaking of campaign slip-ups, Sen. Cory Booker (D), who'll run for a full term later this year, accidentally sent out fundraising appeals to supporters earlier this week asking for $0.
* And yes, even now, despite everything, Toronto Mayor Rob Ford will run for re-election.
