Drudge reporting over a million votes cast overall.
I voted again (as far as I know it counted) Thursday, which is when I saw that Sanders had surged from single digits to over 30%, and Trump was at 32% +.
Sanders peeps rallied to make it close. Interesting lessons.
I voted more than once to see if it made a difference, and saw it said “we have already counted your vote”. So I think it was counting only one per voter.
