my concern about a childish man with no self-restraint or character being in charge of the US.
Yes. I've disagreed with policy decisions by every president. Some more than others, of course. But Trump is just plain bizarre, and he says the first thing he thinks of, truthful or not. The Mexican president cancels a visit? Response by Trump: No, it was my idea all along. Trump's feelings get hurt by facts about the election results or the inauguration ceremony? Decree an investigation (wasting taxpayer funds on nonsense), or shut them down. And today, I heard his statement about relationships with foreign leaders, which was pretty much "sometimes I get along well with people, and others I don't" (meanwhile, I'm thinking "It's your damn job to get along with them on behalf of the US, no matter what your personal feelings.") His behavior is definitely weird and unusual.
And I'm getting more disturbed by Steve Bannon's ghastly influence every day.
