Depends.
Compared to Kerry, probably approve. At least i know that i'm safe with Bush. Sure there are gas prices and all that other crap that Bush gets blamed for, but those things probably would have happened regardless of which president we have.
Compared to the past presidents (i.e. Clinton), definitely disapprove. During Clinton's presidency, there was no sh.t, he got his job done, the stock market was good, the economy was good, nothing was really that bad except his affair with his secretary. Who cares if we had an affair with that ugly biznatch, he was mch, much better than Bush and i'd have him back anyday.
