Last year, the mood in my field, that has been relatively isolated from many of these impacts, was still very "these are uncomfortable times, but it's still possible to pull through".
Recently, you can cut the tension in a room with a knife whenever matters relating to government decision making come up. Some coworkers are leaving science, promising phds and postdocs leaving to other countries, many of the more established scientists are maintaining backup options.
I too have re-evaluated my feelings and decided that while I am not yet at the point of actively looking to leave the US, besides the hassle of moving itself, I would be fine with having to do so.
