Dan, speaking of ’94, I enjoyed this snippet from John Fund on WSJ.com earlier today:

Two weeks before the 1994 election, the magazine Campaigns and Elections summarized all of the leading predictions about the race. Charlie Cook of the Cook Political Report predicted that “Democrats will lose 20-25 in the House, four to five in the Senate.” Stu Rothenberg, the Beltway’s other premier prognosticator, had a similar view: “Democrats will lose 24-26 seats in the House, three to five in the Senate.”
Among other crystal-ball gazers cited in the magazine who are still predicting today, Larry Sabato of the University of Virginia was confident that Democrats would “lose only 24-25 seats in the House and four in the Senate.” Gloria Borger, then of U.S. News & World Report, predicted a 25-seat gain by the GOP, as did William Schneider of the American Enterprise Institute.
[The Daily Beast’s Benjamin] Sarlin notes that current predictions are for Republicans to gain between 50 and 60 seats this year. But what if the expert handicappers are as errant as they were in 1994? We could be looking at either a much smaller Democratic defeat or a GOP blowout of epic proportions, perhaps a gain of 70 to 80 House seats.
