Barletta would be more likely to win if Obama were also on ballot. Obambi is a drag now, with 45 approval ratings and going down.
In a Democrat district such as that one, Barletta is better off with the low turnout that non-presidential elections bring. Barletta will get the benefit of Obama’s unpopularity, but will not have the disadvantage of Obama’s presence on the ballot bringing out all those idiots that had never even voted before 2008.
