Its the will of SOME of the America people. Just because 51 out of 100 people want something, doesn't mean the other 49 should have to cowtow to the (VERY slim) Majority.
I think you're right about this. We're a Democratic Republic, which sets us apart from a pure majority-rules Democracy. The Constitution exists as a stumbling block to slow the progress of change so that the majority cannot get anything it wants unless it's persistent and vast. In the end anything can be changed, even the Constitution can be amended. However, you're misrepresenting the majority of the Democrats (assuming you meant your comments in the context of Healthcare as per the topics). Obama was elected by quite a bit more than a 2% margin and the Democrats gained seats in the House and Senate by a larger margin as well.
You could argue that they're going against the will of the majority, or at least a very large chunk of the population, but there's plenty of ways to debate that too. Personally I'd say they're fulfilling the promises they were elected on, and although the American people may have changed their points of view, they are simply making their promises reality that they made to get elected.
It's an interesting conundrum: should a politician govern by polls or the platform on which they were elected? I defer to the latter because I think the American people make more reasonable judgments over the course of the campaign season and actually try to educate themselves aside from political propaganda during that season. The distaste for current policies can be chalked up to months and months of debate and intelligent (albeit deceptive) political propaganda. The non-partisan information on misconceptions collected by Politifact would certainly agree with me on that.
If a person doesn't want to pay a cent in taxes, well that's their right. they just can't use any Government provided services.
I'm pretty sure that's not written in the Constitution (or anywhere else). You don't have a right to not pay taxes, you're punished if you don't. Granted, you can
always leave the country, then you won't have to.
