I'll start with the war protestor analogy:
The protesting peaked within the first few years of the war. It continued throughout the Bush presidency because of the view that Bush was a war mongering president.
The wars continued under Obama but those angry people became less angry because they perceived Obama to be a peace maker (hell he won a prize). Interestingly, the war activity overall went up but the protests went to zero. Part was general fatigue with protesting and part was anticipation of the new direction.
Under Bush, his real spending boost came later in his term. Many were bothered that he was overspending, particularly on entitlements but it was a relatively small and non-vocal group. His war spending didn't get a big rise because many of the current TP viewed some of the wars as necessary or within the purview of government.
At the end of Bush's term we saw an economy crash. We saw government begin to step in with big spending. The TP was emerging at the time of TARP - initiated by Bush. More people began to believe that government actions were causal effects for the economy. Next, we see Obama come in and use TARP for auto-bailouts. We see the Omnibus spending bill 1 that raises discretionary spending by 12%, we see an ill-formed Stimulus with lots of political payoffs to every Dem wet dream that's been on the shelf, we see the beginning push for Obamacare including singlepayer HC, we see the second Omnibus spending bill that adds another 8% to discretionary funding, we here people aren't paying their fair share, spread the wealth around, Dodd-Frank, rapid growth in government agencies, unprecedented use of Czars, open demonization of business, destruction of contracts with the auto-bailouts, etc. etc. - all this under the control of a president who vows to fundamentally transform America.
The trajectory is absolutely towards a massive shift towards Federal government control. Like the war protests, these actions mobilized people that had been concerned already. Obama absolutely took spending and government involvement to a new level and showed no signs of stopping.
Nah - it's because he's black...
