What has the government done for any of us? Not much, and part of the reason is it was never the intent that our government provides for us.
I consider myself a Libertarian, but I'm on the fence of the whole "throwing your vote" away argument so I always vote Republican. There are things I don't agree with the Republicans about, such as abortion and gay marriage. I'm also non-religious and borderline Athiest. The things that truly matter to me like gun rights, the economy, etc. is what truly separates them for me.
I once heard that voting Democrat or Republican is just choosing what you want taxes spent on. Republicans meant a stronger military, private sector, etc. whereas Democrats want to support more social programs and such.
