Is this the real reason Michele Bachmann quit?

There's an old saying that you should quit while you're ahead. Maybe Michele Bachmann saw the writing on the wall -- liberalism is surging in America:

Economic conservatism has hit a five-year low, according to a Gallup poll released Friday.

And, the survey suggests, "ideological attitudes in the country may be shifting."

The poll found that social liberalism is up six points since 2001 and is embraced by about half the Democrats and those who lean Democrats.

"It is possible that Americans are returning to a certain sense of normalcy on economic ideology, while social ideology continues to charter new ground," said a poll analysis.

Which I guess is a shorter way of saying that the dirty (bleep)ing hippies are winning, again.
