The National Republican Congressional Committee is targeting North Dakota Rep. Earl Pomeroy (D) with a 30-second TV ad airing in his state. The ad aims to put political pressure on Pomeroy to not support a Democrat-written health care bill that could come up for a vote in the next several weeks.

Pomeroy briefly considered running for the state's vacant Senate seat this year, but opted for re-election instead.

"Seventeen years in Washington have changed Pomeroy," the announcer states. "Now he's voting 97 percent with Nancy Pelosi."
