From Forbes:

George W. Bush won the 2000 U.S. presidential election by a razor thin margin and some economists reckon that a weakened dollar could put him back in the White House in 2004 with a comfortable victory.

On the surface, a weak dollar may not seem very relevant to Bush's re-election, but in the five Midwest states where Bush lost by slim margins to Al Gore it could make a huge difference when Americans go to the polls in 15 months.

The falling value of the dollar, which has dropped 35 percent against the euro in the last 18 months, makes goods stamped "Made in U.S.A." less expensive on the global market, boosting exports for U.S. firms that might then need to add
jobs.
