Reihan Salam points to this Barone post on the loss of Denny Hastert’s erstwhile seat.
The issue is one that deserves some attention. In 2000 and 2004, Republicans prospered as the party of the suburbs and especially the exurbs. Not so in 2006.
I’ve discussed these matters before here and here, but am now less inclined to be sanguine about the short-term nature of Republican difficulties. Iraq isn’t the only challenge.
