Yes it’s a closed primary, and if he’s an independent, he shouldn’t even be voting, IIRC. He could have changed his party affiliation in order to vote, and from what I’ve read, many did.
I’m in a heavily democratic district. The only voters at the polls this AM were Republicans (nobody was in line to sign in for the Democratic vote.) Whatever that means, don’t know. Short ballot, just the primary, a tax amendment question and a school tax vote. Took me 10 minutes to get in and out.
Could be because Florida rat votes won't count this time, unless Hillary gets to change the rules,.
That strikes me as odd -- I've never seen separate lines for Republicans and Democrats. Where I voted there was just one line (and it was a long one, at 7 a.m., no less) and there was no way to tell who was voting in which primary. Only the poll workers would know.
