This doctor is an idiot and apparently of the opinion that his shit doesn't stink. All he needed to do to get rid of most Obama supporters would be to put up a few posters around the office...Glenn Beck, Rush Limbaugh, NRA, Dr. James Dobson and Focus on the Family, maybe a military poster or an "America, Love it or Leave it" to affect the stragglers. Voila!
Personally, I don't give a crap about a person's political views. If the dude is a doctor and does his job well, then I'll be there. Otherwise, I couldn't care less about his non-radical political views.
