Why would you see them? Every move is different, and every person has their own motives. Often there are several. I'm not crazy about the direction the US is going, but regardless of the president I really like getting a month a year off.
If this is anything like Brexit affecting London, I don't see lots of people leaving, I don't even notice any difference in my workplace, but I know someone living the UK every month to the point we're not even one year since the referendum and half my friends already left, one by one.
So, point is, you might not see a sudden movement but it might still be there.
