Counter cyclical spending can help stabilize an economy. It can be effective and stimulative efforts from Obama's administration has done some good, the question is at what future cost? The problem with the US is we are always in perpetual deficit, we should be running counter cyclical spending deficits during recessions and surplus during economic expansion. The problem right now is the prior and current debt coupled with massive counter cyclical spending is crowding out some private sector investment. Additionally, it appears that this crowding out will likely become more prevalent as interest rates rise beyond 2012. This will have a significant affect on GDP growth. Most economist estimate that the debt/deficit by 2015 will have a .7 to 1.0% drag on GDP as we move into the latter half of the decade.
Mitt Romney actually has a very firm grasp on monetary and economic policy, you may not like him, but when it comes to economics/monetary and fiscal policy he would likely push the country in the right direction for sustained long term growth.
