Republicans don't care about facts. One of the important facts of economics is that a lot of economic indicators, like unemployment and food stamp use, are lagging indicators. That means they get bad AFTER an economic disaster.
What Romney calls the Obama Economy is really what's left of the failed Republican experiment in supply-side bullshit undertaken during the Bush Administration, in which we had massive tax cuts for the rich that were supposed to create jobs that resulted in an economy shedding jobs to the tune of 750,000 per month when Obama took over.
Furthermore, the debt, which Romney and his magic underwear are trying to also blame on Obama, was mostly created by the Bush tax cuts, two unpaid for wars, and a Medicare prescription drug benefit the total cost of which the Bushies lied about, and for which we have not paid.
That's a lot of failure under Bush that Romney, of course, wants to put in a paper bag, light on fire, and place on Obama's doorstep. So, there's Obama, stomping out the shit fire, and Romney sitting back saying it's Obama's shit, when it's really George W. Bush's.
