Primary story from friend in Tennessee

Woman behind me at polling place: I don't know what to put here.
Pollster: you just need to circle democrat or republican to get the right ballot
Woman behind me: but I don't know!
Pollster: well, you know who you are voting for, right?
Woman: Yes! TRUMP! But is he a democrat or republican?
Pollster: he's a republican. Check republican if you want to have the ballot with Trump.
Woman: oh, he IS? Ok. I didn't know.
