The island of Lincoln

From NBC's Domenico Montanaro
Who, Blanche Lincoln, a Washington, D.C., Democrat?

Lincoln, one of the most vulnerable Democratic incumbents running for re-election this year, is up with a new ad seeking to distance herself from Washington -- and the Democratic Party.

The ad depicts Washington as rowdy schoolchildren. "This is why I voted against giving more money to Wall Street, against the auto company bailout, against the public option health care plan, and against the cap and trade bill that would have raised energy costs on Arkansans," Lincoln says in the ad. "None of those were right for Arkansas. Some in my party didn't like it very much. But I approved this message because I don't answer to my party. I answer to Arkansas."

The ad is running from March 5-12 statewide. A Lincoln source calls it "a substantial buy."
