I’m reasonably sure this is going to change dramatically after ObamaCare passes, but let’s enjoy the class-warrior irony while it lasts.

The Democratic-controlled House is now an unusual combination of the richest and poorest districts, the best and least educated, and the best and the worst insured. The analysis found that Democrats have attracted educated, affluent whites who had tended previously to vote Republican.

Democrats now represent 57% of the 4.8 million households that had incomes of $200,000 or more in 2008. In 2005, Republicans represented 55% of those affluent households.

“Democrats have made enormous gains in affluent, educated suburban districts,” says Warren Glimpse, founder of Proximity, a firm that analyzes demographics. “What’s not clear is whether this reflects a profound change or a temporary blip.”

Megan McArdle peers into her crystal ball and sees … a cloudy future:

I think it is more likely is that this thing passes, and fails spectacularly. There are too many moving parts, and if any of them breaks, the whole thing rapidly starts to spin out of control and eat a gigantic hole in the deficit. If it does break, I think that Democrats keep control of Congress just long enough to explain why they keep having to enact whopping new tax increases every few years. Republicans don’t need to improve their message. They just have to wait for Democrats to recover their reputation as tax and spend politicians who woefully underpredict the cost of everything they propose.

It’s pathetic that the GOP’s losing successful entrepreneurs to the left, needless to say, but presumably next year’s reorientation will straighten them out. Meanwhile, in the eternal swing state, Specter’s re-election numbers are “near fatal” according to one pollster, although I suspect that has more to do with his weaseliness than his fondness for government expansion. Rasmussen’s latest temperature-taking of likely voters: Toomey 45, Specter 40.
