Daniel Gross has a post up today at Slate "CEOs for Clinton: Even the ultra-rich are abandoning the Republicans," which affirms the trend noted by J. P. Green's post below, American Prospect's Paul Waldman and Christopher Hayes at Washington Monthly back in June, among others. Says Gross:

Back in 2000, George W. Bush called his base "the haves, and the have-mores." But the have-mores are clearly more receptive to Democrats than they were seven years ago. "It's a much easier pitch drumming up support this cycle from business people, there's no question," says Steve Rattner, founder of the private-equity firm Quadrangle Group, who is a longtime Clinton backer. His take: Fed-Up CEOs are reacting to the bungled war in Iraq, poor fiscal and disaster management, and conscious outreach efforts by Hillary Clinton and Barack Obama.

It's not all CEO's of course, Gross hastens to add, and he likens the rash of CEO contributions to Democratic candidates to a hedge bet. But the momentum does seem to spell trouble for the GOP -- especially when it comes from one of their most reliable constituencies.
