Nuclear disarmament probably won't happen until they are made technologically obsolete, probably around mid-century.
Infrastructure is neccessary, as is constantly improving it. Loss vs gain, infrastructure is a sound investment.
Public student loans cut out the middle men, giving both better rates and rates which won't increase by 50% unexpectedly.
Technology = good; technology is pretty much the only thing which will keep us from being dominated by China militarily, and more importantly, economically.
As far as tariffs go, I'm pretty neutral: low rates increase outsourcing, but high rates make goods expensive here.
Medicare seems to be more of a stopgap measure in its current form; without further healthcare reform it will become extremely expensive.
Taxes: we need more. The services demanded of a modern government require relatively high taxes; but such is the price of civilization.
Abortion: In a perfect world, all babies would be born smart, pretty, and with wonderful parents who provide everything they need to develop into good citizens and tend to the herds of bunnies, kittens and unicorns. However, this is far from a perfect world. In reality, most of the children born would end up abandoned and their care would have to be taken up by the government; a government already chronically short on funds. That of course is assuming they were born. Even with laws banning abortions, the rate would hardly decline. The only difference would be that they would be done with coat hangers or razor blades in a bathroom instead of in a sterile facility, likely causing the death of the woman involved.
Gun control: Somewhat impartial here, although more regulation is probably a good idea.
Now back on topic. Nilocy, the problem with that is people are lazy. And quite frankly, having people vote who aren't informed of the issues is just dangerous. Keeping up with politics requires multiple hours a week, much more effort than most are willing to put into it.
