Those could be a propaganda smoke screen to depress the Trump vote at this point. If Trump supporters think he has it, they won't prioritize voting, they will prioritize their kids ball game, or the weekly gathering at the watering hole, etc. The establishment will do anything to keep folks that support him away from the polls.
Why do you think the establishment has always made traditional voting days on a Tuesday while folks are at work all day? IT's for nightmare scenarios such as these. The weekend ones will have much bigger turn outs. But all the BIG states will all be on a Tuesday.
And all the propaganda geared to get folks to not vote for their candidate or keep them home will be geared to that message.
