"Are you actually suggesting that the entire election nationwide should be re-envisioned based on a single poll?"
No, I'm saying that it is incorrect to claim that a Democrat tsunami is in the works based on summer polls of national adults. The recent generic congressional ballot is no more trustworthy than those from earlier in the summer, but it is no less trustworthy either. I think the correct baseline when measuring states and districts is electoral performance in the 2000, 2002 and 2004 elections, maybe with a slight tinge away from the GOP based on the national mood, but nothing that would indicate that Democrats will suddenly becomedominant in districts that voted for Bush and the GOP House candidate in 2000, 2002 and 2004.
