1. Bernie Sanders
2. He is honest and authentic. An "honest politician" is an oxymoron,yes, but it applies to him. Even better, his proposals, once you understand them, actually make sense. And this is coming from someone that considers herself to be a fiscally conservative Independant, that has voted for "R"s for most of my life, has an MBA, and works in the treasury of one of the biggest companies in the world. I don't just like Bernie "because I want free stuff". His proposals won't help me, except in the sense that they help the entire country.
3. HRC, Trump, Cruz, or any of the other "R"s
4. HRC and Trump want to be president for their own personal power trips. They will lie, cheat, and flip-flop on any issue if they think it will get them elected (HRC: against marriage equality, now for it; for the TPP, now against it) (Trump: "I watched in Jersey City, N.J., where thousands and thousands of people were cheering as that building was coming down. Thousands of people were cheering." -- yeah, whatever, donald. It CLEARLY never happened). Trump's racist, misogynist, narcissistic rantings are simply unbelievable.
Cruz and the other "R"s are probably more honest than HRC and Trump, but what they want to do to this country, and the world, is just down right scary. Every one of them one-ups the other on wanting to send our kids to war in the Middle-East. Because, you know, it worked so well when bush did it. And, BTW, spent $3 trillion TRILLION(!) dollars of our money in the process.
