"which was mostly used to shore up the existing salaries and pensions of his political base"
I've got bad news for you - the stimulus pretty much all went to government contractors, the vast majority of which are controlled by, and for the benefit of, right-leaning individuals. The money was spread far and wide, so at the ground level it's probably 50-50, but those folks do nothing but vote and none of them give enough to campaigns to make it interesting. I don't remember huge stimuli for the entertainment industry, or for union organizations directly, or hiring government workers (unless you count the money given to states for police officers and fire fighters...which, again, aren't exactly the biggest bastions of Democrat love). If you're talking about the bailout of the auto industry which kept all the union workers from being unemployed, that was Bush.
Not that it matters - the original goal was to keep oil in the country to avoid corporations selling "our" oil to others for profits when the middle east was giving us the finger. And, really, the high cost of gasoline and other refined products is still a result of us selling our refined products internationally where the companies can make more money. Everyone complains about the high cost of gasoline, and how we must drill more to become energy independant, when in reality we produce so much excess fuel that it was *the* greatest US export in 2012. Our gas prices are high because other countries are willing to pay more for it than we are. That's not to say that our policies aren't protectionist, but there's a huge gulf between where we are and where we could be if we wanted to be selfish about it.
