You have certainly a good imagination. And this is the racist crap that is off putting to say the least but now expected from a certain crowd.
I will say it now...if Clintn wins the nomination these politics of personal destruction will have zero effect in my state. For all I care Dems could nominate Caligula and he would be elected. But they will in swing states. Sanders supporters are telling you in no uncertain terms they will stay home because of them. Sure some of that is bluster, but some will. Say hi to President trump. And I will "blame" since it will have to be assigned, Clinton supporters. I got very personal reasons to consider a good chunk racists by the way.
Oh and continue to blame the wrong people for this. The fact is, this is the Nevada party machine at work. They are responsible. They knew this was not going to be a caucus that would be majority monolingual (English) so yes I blame the party.
Whether this was on purpose ( which would make it ten times as bad), or just an oversight is a very good question.
