If Obama inherited an economy as strong as Bush did and had the Twin Towers obliterated on his watch and invaded a country over WMD they didn't actually have, I absolutely would not vote for Obama again. As it is, I haven't decided on voting for him in 2012. It all depends on who's running against him and what state the economy is in at that time.
Once again, you confuse nominal dollars with real dollars along with the reason for using real dollars. In the real world, 2010 showed 2.9% growth, which is better than 6 out of Bush's 8 years:
2000 11,226 4.1%
2001 11,347 1.1%
2002 11,553 1.8%
2003 11,841 2.5%
2004 12,264 3.6%
2005 12,638 3.1%
2006 12,976 2.7%
2007 13,229 1.9%
2008 13,229 0.0%
2009 12,881 -2.6%
2010 13,248 2.9%
Hey, look at that ... you must think Bush was president only until January, 2008. Why did you stop there? Oh ... here's why ... over 4 million jobs were lost during Bush's final year ....
