If you'd like I can provide further data supporting my claim from Ivy League economics departments, third party Federal spending sources, nonprofits such as the one the charts came from which provide good objective data on where a variety of candidates stand, and the odd news article and book.
I'd also like to add that the good things involving the economy are not 100% attributable to Obama, as he actually as little to no direct control over the economy because, again, we're not a socialist state (again, contrary to what the right has been shouting for years).
