I'm a leftist(demsoc), but frankly if they're willing to work without hostility toward their coworkers I am not particularly concerned with their positions on taxes or whatever. In fact I view the idea that someone can be fired because of their political position as a threat to labor rights. Excluding of course any positions relating to protected classes such as gender, age, national origin, disability. If you think your coworker shouldn't have the right to be there and are creating a hostile environment, you're the one that has to go not them. Otherwise yeah I have no problem and have happily worked with those who I believe are fundamentally eroding our democracy :V.
