Thanks for your question... political speech in most states is not a legally protected trait or characteristic - so making frequent political jokes that others find unwelcome and offensive would typically not be a legal problem, but it's still a culture and respect problem as that behavior lacks respect or sensitivity to others on the team who have a different perspective.
A culture/respect problem is still a problem and the person making frequent political jokes should be coached as to how the jokes may negatively impact others on the team.
Hope that helps.
