I think the number is probably closer to 65, but you’ve got a point. Add to that the dissatisfaction the conservatives had with the GOP in ‘06 and the scandal after scandal the Left perpetrated to get elected (Ted Haggard, Rush Limbaugh and the Michael J Fox thing, Tom DeLay— they went everywhere)... there is huge opportunity for bounce-back this year. The Democrats are blowing it and losing whatever support they had coming into the year.
