Should you talk politics at work?

For the past few weeks, I have been wondering if politics at work is healthy or toxic? I'm curious, what impact are discussions on politics having on our work cultures and professional relationships?

We know that across the country, some families and friends feel a great divide politically and some have even avoided talking to each other. But at work, we don't have the option to just stop communicating.  We are expected to lead, drive results, and produce regardless of our politics. So the big question is...Should we talk politics at work and how is that working out for us?
