Similar experience:
My cover band (60s, 70s) finally got to play out last weekend because bars are allowed limited seating in eastern PA.
I had so many people start out the conversation talking about Covid19 - many saying the economy never should have been shut down. Then they say something about it being politically motivated. Then, before you know it you are having a pro Trump conversation!
You are right that most Trump supporters normally keep quiet about it.
But people do speak freely about the pandemic, and the interesting thing is that you can tell someones politics by how they talk about the pandemic.
So it seems to be a segue into politics and you can gauge the politics of who you are talking to.
I had no idea there were that many people were secretly pro-Trump.
roger that
