Both sides are to blame - neither will fix the problem. Obama could've made that his goal - he was competent, had a lot of political good will, and many people were frustrated at the bailout policy Bush did, but instead it was inflationary printing (quantitative easing), Obamacare and Cash 4 Clunkers (which the used car market still hasn't recovered from).
I never voted for him - I didn't view him as honest, nor did he seem to indicate that he liked America, but was rather just a good talker - but I think he could've been a great president given a less radicalizing agenda.
He was probably the best situated president in terms of timing to fix the debt problem, but instead it was a good time for divisive politics. By the time Obama finished, it became clear neither party actually cared about the fiscally conservative Ron Paul supporting voting block.
