Matt Yglesias says all that needs to be said, but the bottom line is this: Sen. Michele Bachmann does not see the difference between China making a recommendation about what currency to use as the reserve currency, and the institution of a sinister One World currency, outlawing the dollar.

It was a mistake she made two days ago, when she read about China hoping to switch to a different reserve currency.  You would have thought that someone on her staff, or perhaps someone in the Republican leadership, would have taken her aside and explained to her that she's showing her ignorance.
