i am a bit inclined to put bush ahead of clinton strictly because bush stuck to his guns for the most part, did what he believed in, and didnt bow down to the polls. clinton, while i strongly prefer his ideology to bush, was a politician first and foremost.
obama is by far better than both of them, an intelligent pragmatist with full knowledge of the weight of his actions, doing his best to seek common ground with republicans wherever possible, even when its extremely politically risky/unpopular among his base. id prefer if he was still the guy in the campaign, but the heavy responsibility of the office has made him into a more cautious and moderate individual.. he could have carried his momentum into the presidency and hammered away at the big issues that got him elected.. universal healthcare.. gay marriage.. sweeping economic reforms.. etc.. and eventually gotten enough public support that either the republicans in office would have to make consessions or they would be voted out and replaced with people who would back the president.. but alas he did not do so.. but now im just ranting...
