If I recall correctly, those cuts were strongly criticized at the time as being unsustainable and likely to lead to huge budget deficits. Rather than fix the core financial problems at the time, a tax cut was used to punt unpopular measures into the next administration.
I guess those problems could continue to be ignored for the sake of popularity, but that plan hasn't worked very well so far.
Edit: For the downvote brigade; no, those cuts did not help you: http://www.economist.com/blogs/freeexchange/2009/01/tax_cuts...
