1) For which candidate are you voting?
Clinton.
2) Why?
I like Bernie, and I think his politics align more closely with mine than Hillary's, but he's ultimately an unrealistic choice in my opinion. He simply doesn't have the political currency necessary to implement his (admittedly good) plans. Hillary is more centrist, which means she has more sway to get things done.
In the choice between cynical practicality and optimistic idealism, I come down squarely in the practical camp.
3) Which candidate would you least like to see as the U.S. president?
Pick a Republican, any Republican.
4) Why?
Too many reasons to count. Republicans are an absolute nightmare on domestic social policy. They want to restrict abortions, roll back and block gay and trans rights, ramp up executions, ramp down gun control, ruin what little sex education exists in this country, and upset the place of science in policy in favor of religion. Economically their policies serve to enforce and increase a wage gap that leaves most of the wealth in the hands of a few, leaves businesses free to pollute the earth and the political system with impunity, and do nothing to help balance the scales between the patriarchal few and the varied many. Their foreign policy has degraded from TR's "Walk softly and carry a big stick" to "Hit not-Americans with sticks." Some are worse than others, but they're all bad in their own special ways.
Basically, the end of the story is that I'm a total yellow dog democrat. Put my sister's chihuahua in the democratic slot and I'll pick her over the demons on the right. At least she's cute and only pees on the floor sometimes.
