Crossroads GPS, the conservative 501 (c) (4) that counts former George W. Bush advisor Karl Rove as one of its chief architects, announced yesterday that they were broadcasting ads targeting what they believe to be a dozen or so of the most vulnerable Democratic incumbents in the House of Representatives.

Among their targets: Long Island Congressman Tim Bishop.

Bishop represents New York’s First Congressional District on the eastern end of Long Island, one of the state’s quintessential swing districts.  Bishop beat Randy Altschuler by a few hundred votes in 2010, in a race in which the counting dragged on for months, and this year Altschuler is planning a rematch.

Crossroads GPS is credited with engineering the Republican takeover the House in 2010, and in this ad they try to hang Bishop’s own words against him and tie him to increased government spending.  According to a campaign source behind the ad, Crossroads is planning on spending $225,000 to air the ad over the next several days.
