I have serious concerns about his treatment of women. For example, his ex wife wrote many years ago about how he violently raped her.
And the whole "Nazi symbol" situation. I still can't believe he hired someone to do the sieg heil twice at his inauguration.
Wait... who were we talking about again? I guess I can't prioritize certain things as long as the bar-lowerer-in-chief still holds the highest office in the land.
