To answer your question as to whether there is any candidate that would make me leave my home country............
My husband and I actually had a conversation along those lines today. If we were younger , say in our 40's we would seriously consider leaving this country if any Republican got into the White House. The unfortunate thing is that there are so many countries in the world that are not worth moving to because they all have similar problems: bigotry, racism, misogyny, homophobia, unbridled hatred, wars, etc. What it comes down to is we have more people willing to bring their hatred out in the open and actually act on it. Kindness, intelligence, humaneness, care of others, working together to make things good for everyone - those things are slowly being erased from the American scene and replaced by, for want of a better word, idiocy.
Don't you want to live in a country that prepares for the future, not turning it back into the nightmare it used to be for many of our citizens who are not White, Christian and male? The current breed of Republicans seems to base their world view through their Bible, their homophobia, their racism, their greed and hatred. Who wants to live in that kind of world? But that's what the United States will become if any Republican gets in to the White House.
