Candidate Bachmann and the price of gas

I'm on my phone so this link likely won't work, but let's make sure we follow this story: Bachmann promises $2-a-gallon gas http://usat.me/415730 . The lack of economic understanding among U.S. politicians is disheartening. Doesn't each candidate have advisors who understand and can help them avoid nonsensical promises? (And another thing, recent Fed policy has done nothing to the value of the dollar. Railing against the Fed makes very little economic sense.)
