I'm generally apolitical, but in a strictly ideological sense, I definitely lean conservative and libertarian. Why? Because liberals want progress, and progress nowadays is defined as improving the lot of the unfortunate, like the poor, elderly, and sick. However, this is accomplished by taking from the prosperous, young, and hale members of the population, which includes me. I don't like the Affordable Care Act because it means that I'll be paying more for health insurance to subsidize those with costly health problems. I don't like Social Security and Medicare/Medicaid because they're incredibly expensive programs, and all the money comes from people like me. I don't support a large military and foreign intervention because, you guessed it, those things are hella expensive and reflect their cost in the higher taxes that I pay. In fact, I would not support any government program that does not benefit me.
This is the conservative ideology, though nobody is brave enough to admit it. Liberals want to help others; conservatives want to help themselves. To give as little as possible and get as much as you can, that's the American way. Anything else is just idiocy.
Of course, as soon as I cease to be a productive member of the workforce (i.e. retire), I'll instantly be in full support of Medicare, Social Security, and anything else that helps out old people at the expense of the young. Again, it's just common sense. Why would I care about millions of people who I'll never meet when it goes against my self-interest?
