A Colorado landlord knows what kind of person he will not rent to.

FOX's Kerin McCue reports:

Mark Holmes is a homeowner in Grand Junction, Colorado. He's posted an ad for a two bedroom apartment for rent that's part of that home. But supporters of Donald Trump need not apply. And he's got the law on his side.

He knows he can't discriminate against potential renters on the basis of sex or race. But he can refuse to rent to someone if he doesn't like their political affiliation. The 62-year-old landlord says he doesn't know what to do about the possibility of a 'President Trump', but he does not want to live above anyone who would vote for him.
