But your math doesn't tell you Obama is cleaning up the mess Bush left?
Actually, quite the opposite--because despite a Democrat-led Congress, Reagan LOWERED taxes overall, and despite the tax increases he did pass--which were supposed to be countered by $3 in spending cuts for every $1 in tax increases--a promise on which the Dems reneged--the economy was in far better shape by 3 years into Reagan's first term than we are three years into Obama's.
You can in fact draw some significant parallels for about the first 12-18 months, but after that point, you have to admit that if any sustained, measured improvement were to have occured under the current administration, it would have occured by now.
The fact that it hasn't shows that Obama's policies are in fact COUNTER-productive, and a second Obama term would be an outright disaster, especially come around 2014.
