Fair enough. The prison population, and the draconian sentences the justice system imposes, are outrageous. But that's a reflection of what the people want. If people did not vote for politicians who spout "tough on crime" nonsense, we wouldn't be in this situation. So first and foremost, we should look at ourselves, and not the government. The establishment's main worry is to keep their jobs and power. Change the criteria for that, and you'll change the political environment.
We can argue about which regulations make sense and which don't. But many of these are not increased restrictions by the government. Weed for example has pretty much always been banned (unless we're taking a long historical view, which makes no sense in this context). It has been banned because the population at large saw it as some evil drug that's luring their children, and they worked to stop it. The view on marijuana has very recently become more liberal by the majority of Americans. Consequently, you're seeing a trend of legalization across the country.
Again, this is not a discussion about the best possible candidate. It's about the candidates we have. And an establishment candidate, with all the flaws of the establishment, is a million times better than Donald Dump.
