Voting based on ONE platform: my anecdotal frustration with an older voter.

Is something I know my older relatives to do, and is something I think is the stupidest thing one can do.

I was sitting shotgun while my older aunt drove me back to the university.  She said she votes republican because she is against people getting benefits while not doing anything.  When I asked her if she believes in going to war.  She said no.  When I asked her about climate change.  She said she believed in it and that we should do something about it.  Those were the only two platforms I could think about at the time.  I didn't ask about gay rights, abortion, death penalty, guns, and drugs, but when I did ask about other platforms she may believe in, she didn't have any.  She votes Republican based on one platform and ignores all the other platforms even when there could be quantitatively more democratic platforms she could agree with or find important if she knew about.

It seems to me she only cares that the lazy people don't get any benefits (she may not be lazy, but she gets this support as well).  Nothing else matters to her, and she isn't even honest about the fact that this is the case.
