Well, I'm just wondering if it might be, but there is one major concern in my books. Let's say that there is a uniform 5% swing from GOP to Dem (compared with 2004), how many GOP congressmen would go down and how many INCUMBENTS would go down? If what I have heard is true, the answers will be less than 50 and zero for the second one.
Well, in a certain sense, you're asking the best case scenario. The problem is, that this never happens. There are certain incumbents in danger CDs whose support will hold on and others who won't. Also, the simple fact of being incumbents makes them stronger than they would otherwise. The GOP has done a fairly good job of keeping those incumbents in marginal CDs this year, but still some are still vulnerable. Keep in mind, also, that scandal could affect other incumbents that are not within this window.
Anyway, I saw this posted on another site by a poster I respect greatly on these matters. If you compare the Congressional partisan index (this is what Charlie Cook uses to gauge House races) from 1992/1996 and the one from 2000/2004 against the seats won in 1994 and the seats that are seriously in contention in 2006, you come up with this fact:
If the Democrats were to achieve a reverse 1994, a respective mirror of those results, they would gain somewhere in the range of 18-24 seats in the House.
