"People say they don't like partisan gridlock in Washington. But they're voting in ways almost certain to increase it, by punishing politicians who cooperate with the opposing party and rewarding ideological purity that pushes both sides to the fringes," Associated Press reported. Examples include the primary defeats of Sen. Arlen Specter, D-Pa., and Sen. Bob Bennett, R-Utah, two lawmakers known for reaching across party lines. Such moves away from the middle hurt our country's ability to address difficult problems. For example, AP reported, "efforts to revamp energy, immigration and other big policies have flagged largely because of partisan divisions."
