I don't believe its as likely as other extremist scenarios.
If anything, I worry that we'll slide into a socialist-corpratist union. We had a similar result ~75 years ago when the Great Depression occurred. FDR was given massive amounts of power after Hoover's blunders, and in turn enacted so many socialist acts, he nearly turned the nation into a full-blown communist state (albeit with Democratic elections). He enacted Social Security, the CCC, FHA, and sought to destroy business competition by cozying with big businesses which he saw as 'saving' the economy (read up on FDR and charges of Fascism).
Such a scenario could happen again - massive increases in governmental oversight on businesses, protecting a favored few, while government offers more monetary redistribution - taking from the rich and giving to the poor. Of course, given that its America, such results will be disasterous as par the course for wealth redistribution in America (see: Social Security, Medicare, and other redistributing programs in America)
Back from the dead, I'm afraid.
