Obama is just one man; behind that man is a multi-administration Party.
Bush is just one man; behind that man is a multi-administration Party.
Both Parties have platforms, and those platforms have planks, and those platforms hold true regardless who is in office.
Obama is who the Democrats selected to go up against who the Republicans have chosen, and it's the Party that makes the choice of candidate held up to a platform standard.
Obama is not running against Bush but against the people who thought Bush was a good idea for not just one but TWO terms.
It's a question of a track record of a Party, and there's one Party whose track record of good judgment is spottier than the other.
Right now, Romney's record isn't standing up to much scrutiny and what's actively withheld from scrutiny is his tax returns. All in all, Romney has a problem with scrutiny. Now then--as Romney runs against Obama, which one's the bigger pig in the poke?
No contest.
Nice try. At least you're starting to figure out that campaigning against George Bush is a loser strategy for 2012.
Now, to address your direct point, O's hurdle is to convince the American public that raising taxes is preferable to lowering taxes, that increasing spending by a gigantic amount is preferable to raising spending by merely a large amount, and that government directions to problems are preferable to private choice. Good luck!!!
