sorry, but you simply don't know what the fuck you're talking about. Legislation requires a simple majority. Only constitutional amendments require a supermajority per the constitution. Cloture and Filibusters are merely a senate rule, and can be changed if the senate so wishes it - in fact they need to be changed as the "filibuster without consequences" we have today is being abused.
The Health Insurance Reform act is entirely constitutional as set out by standing caselaw, as is the "individual mandate" (the item most claimed to be supposedly unconstitutional) as it is merely enforced by tax code - tax code is something the federal government has broad and explicit authority on.
The entire idea that "the only goal of government is to make itself bigger" shows a warped view of the world.
The only goal of government is to serve it's protect - to protect them from threats both foreign and domestic, to help them secure the fruits of liberty and prosperity.
Sometimes the best way for the government to do some of those things is to do nothing, some times it is to enforce regulation, sometime it is to raise an army and defend against an aggressor, and sometimes it requires removing the greet motive from interfering with security the fruits of prosperity for the most people.
The idea that "the smaller the government the better" means that the best form of government is no government. Guess what happens then? warlords.
Stop thinking about politics in macros and soundbytes and start actually thinking.
