The US Dollar is a piece of paper that only has value because it's "backed by the full faith & credit of the US government". They destroyed the value of the US Dollar by creating massive deficits.
They signed a pledge to destroy government credit & "shrink government small enough to drown in a bathtub"
This is why we had massive inflation under Bush & Republicans. There is no such thing as a tax cut when government creates money. You either pay for spending or pay $200 for oil. Only spending cuts reduce cost.
Notice Republicans did not sign a pledge to never increase spending! Republicans explode spending, deficits, debts, prices & INFLATION!!!
