Why Repubs try to suppress the vote
GOP Hopes Rest on Low Turnout
White House strategists see low November turnout blunting Democrats’ edge in polls," according to Washington Wire. "In nearly all 2006 primaries so far, turnout has fallen below 1982-2002 midterm average. One exception: above-average participation in Connecticut’s Senate primary nominating antiwar Democrat Lamont over incumbent Lieberman."
Hotline On Call: "The key to analyzing this trend properly, we think, is to remember that for Dems to retake control of the House, they'll need high turnout only in four or so states with several House race toss-ups each (Ohio, Indiana, New York, Pennsylvania).... as well as high turnout in about a dozen other districts. Unless they're going to pick up the Senate, too, Dems probably don't necessarily need a higher share of the two party vote nationwide."
