Anne Romney raised new questions this week about GOP darling Mitt Romney's integrity -- and claimed that Mitt's unreleased tax returns contain "ammunition" for political opponents.

Jaws dropped when multi-millionaire Romney proudly claimed to have paid less than half the federal tax rate for his income bracket in each of the last ten years.

Despite such a dubious accomplishment Anne Romney defended her husband, saying "Mitt is honest, his integrity is, is just golden."

Such provocative claims raise questions how a presidential contender could possess golden integrity while flip-flopping on matters of strategic national interest under pressure from billionaire donors.

Anne has yet to explain how her husband's "golden integrity" would allow him to flip from recognizing in 2003 that toxic emissions from coal-fired power plants "kills people" to flopping in 2012 to say "We have 250 years of coal... why in the heck wouldn’t we use it."

Anne has yet to reconcile her claims of how a man of such "golden integrity" could shift from recognizing that "human activity is a contributing factor" to expeditiously declaring "we don't know what's causing climate change" in order to solicit millions from extremist billionaires.

Republican or Democrat, Americans are not going to support a shifty politician who is easily bought and sold to the highest bidder.

While claims of "golden integrity" are easily made, they also raise expectations for Mitt to demonstrate he is indeed a man of such mettle.
