As far as discussing politics goes, I am naturally curious as well as cautious with people I don't know well. So when a question comes up on US politics - I am far more likely to at first redirect the question to understanding how the questioner sees things and what led them to ask...that also gives me a clue on whether to explain I live in Texas or live in Austin
When riding the Great Divide, we often encountered local people who asked us what we thought of Trump. My buddy would reply "We don't talk politics. We talk about the weather, the beautiful scenery, how friendly the people are".
The usual response was a smile and good wishes.
