The bottom line is that it is extremely wise and business savy NOT to bring up politics or religion into your place of work or mixed (unknown) company. History has proven it leads to a dead end or the unemployment line. You better make sure you leave nothing important on your desk so your dem coworkers don't get hold of anything to set you up for failure as petty revenge.
I am pretty safe. Out of 30 employees two of us are Republicans, the owner and myself. I especially like to bring politics up in front of him so I get to watch everyone squirm, it's great!
