I've been trying (in my usual long-winded way) from time to time to explain why GOP bashing is not quite the Democratic answer to tea-baggers and other protesters out there these days.
Frank Rich gets it in one sentence [although I had to suffer through an article about Glenn Beck to find it]:
Many of those Americans may hate Obama, but they don’t love the Republican establishment either.
As a political observer [and not as a shill for libertarianism] I think the mood of the public is increasingly populist, while the leadership of Democrats is increasingly progressive, and what's left of the leadership of the GOP is increasingly reactionary.
Despite the fact that populists and progressives both generally share a sense of the necessity for government activism, very little else actually unites them in terms of policy prescriptions, and some of the antipathy toward Barack Obama is as much anti-intellectual as it is racist.
