George W. Bush didn't waste much time once he took office to press for tax cuts: in June of 2001, he signed into law a measure that would result in a $1.35 trillion tax cut over ten years. Shortly after the Iraq invasion began in 2003, Bush signed another tax cut bill into law; this legislation cut tax revenue by another $350 billion. John McCain's reaction to these and other tax cuts as well as the subsequent renewal votes, illustrate some of his most dramatic position shifts.
