This is unfortunate - and I can't help but wonder why your manager or supervisor tolerates this kind of disruption. A tension-filled workplace will never be as productive as a harmonious one, no matter what the cause is.
In the meantime, do what you can to bring peace to your office. No doubt you have your own opinions about political matters, and discussion is important in our political system. But if it's only going to cause conflict to discuss politics in your office, then it's best to keep your views to yourself. The Bible reminds us that "There is a time for everything, and a season for every activity under heaven ... a time to be silent and a time to speak" (Ecclesiastes 3:1, 7).
But beyond this, seek to be friendly with everyone in your office, and reach out especially to people who've been caught up in this. A gentle word about your concern could have a great effect; some of them may not even realize what has happened because of their enthusiasm. The Bible says, "Peacemakers who sow in peace raise a harvest of righteousness" (James 3:18).
Most of all, pray for those around you, and ask God to help you be an example to them of Christ's love and peace. The things of this world will fade, but Christ's love will last forever.
