They may be people who are going to vote for Obuma no matter what because he’s black.
I’ve met a few older people who feel that way. In some cases (I’m sure not all) it’s because they were somewhat racist in their views forty or fifty years ago. They feel that by voting for Obuma they can “get right.” Expiate guilty feelings they harbor from long ago.
I believe at least one member of my own family is in this catagory.
Could be, but it's also possible that they are Democrats, and can't see themselves ever voting for a Republican candidate. Now that I think of it, I recall them saying they were thinking about voting for Hillary if she was nominated. It's funny, because my friend said her father had been a die-hard Republican. And in my family, my father (a railroad worker and member of the union), told us we all had to vote Democrat. In my Dad's case though, I know if he were alive today, he wouldn't recognize the Democrat party, and would probably be a Republican now.
