House Democrats will start airing their second spot today targeting freshman Rep. Dan Benishek (R-Mich.) in the competitive 1st district race.

Democrats shifted their line of attack in this advertisement, targeting Benishek for voting “to give Members of Congress taxpayer-funded health care. For life,” an announcer says.

Benishek faces a rematch with former state Rep. Gary McDowell (D) in one of the highest-profile races in the country. Roll Call rates the contest as a Tossup.

Like every House Republican, Benishek voted in July to repeal the health care overhaul law. Part of that law requires Members of Congress to receive health care from public insurance exchanges instead of the current federal employee program.

The Democratic Congressional Campaign Committee will spend $51,000 to air the spot in the Marquette market, according to a source with knowledge of the buy. House Democrats already aired a spot targeting Benishek on Medicare in the nearby Traverse City market last week — their first independent expenditure of the fall campaign advertisement season.
