Sanders is a crazy Socialist who wants to turn the US into a Communist State. He's a bitter, old man who is a failure that could never support himself and spent his life cursing successful people. He's also a hypocrite who voted in favor of the Iraq War, voted against a bill to audit the Federal Reserve, gave tax breaks to Lockheed Martin in Vermont in exchange for campaign money, etc.
Cruz is a crazy religious windbag that will attempt to turn the Middle East into a glass desert in the name of God and will be a terror stateside to anyone who is not a white Christian male.
Clinton, Rubio, Kasich, etc are all empty suit puppets that are controlled by the same corporations that controlled W Bush and Obama; Koch Brothers, Lockheed Martin, Texas Oil, Wallstreet, etc. They will do whatever their lobbyists tell them to do; Iraq War, GM bailout, etc. If any of them reach the WH the blood of thousands of young servicemen and women/children will be on your hands when they invade Syria in the name of freedom to line the pockets of their lobbyists.
