cross your fingers

All these news accounts and polls about the Democrats' chances in the upcoming elections make me nervous. This article says some political scientists are predicting a "wave" along the lines of 1994 or 1974 that will sweep the incumbent party out of power.

I hope they're right, but with all the obstacles the challengers face -- the tendency to support YOUR incumbent while wanting others thrown out, increasingly effective gerrymandering, etc -- I still won't believe it 'til I see it.
