Not many people know that it was a mere 33% of the population supported the invasion of Iraq without UN authorization. Of course our government did it anyway with bipartisan support.
There was a lot of frustration with the war. The Democrats swept into power in 2006 first and foremost due to public opposition to the war and the perception that the Democrats were against the war. Despite that policies remained unchanged.
Bush gave us a banker bailout. This poll indicated it was supported by 7% of the population. The contempt for public opinion here is pretty striking.
Obama was recently rebuked by Congress for some light hints that suggest the US frowns on Israeli settlement construction, though Obama isn't forbidding the construction. This despite the fact that Americans opposes settlement construction by a margin of 49 to 22% with the remainder undecided.
Americans for a long time have supported a public health care option, whether single payer or otherwise. See here and here. This view has been disregarded for years. In fact Kerry wouldn't even talk about it in 2004 because a public plan was "politically impossible." That's true. It only had overwhelming popular support, but that's not what makes something politically feasible. Now Obama has given us a half assed solution. Mandated purchase of rip off private insurance.
Obama's record on war and civil liberties mirrors Bush as I've already outlined. This is contrary to the desires of those that worked hardest to get him elected. Naturally they feel betrayed.
Cheney slipped up a while back and let us know how this really works.
CHENEY: On the security front, I think there’s a general consensus that we’ve made major progress, that the surge has worked. That’s been a major success.
RADDATZ: Two-third of Americans say it’s not worth fighting.
RADDATZ So? You don’t care what the American people think?
CHENEY: No. I think you cannot be blown off course by the fluctuations in the public opinion polls.
The public is utterly irrelevant to our current politicians. It's no surprise that the public distrusts government.
