Two comments. Independents have never been able to vote in this election and secondly, AZ is a state that allows you to request and submit and mail-in ballot. Long lines eliminated, problem solved. I will say standing in line for hours is a bit over the top.
Maricopa county screwed up, there’s no way around it. They cut polling places by more than 2/3 since last time around. Certainly people should take advantage mail and early balloting, but there is that crowd that wants to vote on election day only, and really there was plenty of data out there to expect a big turnout.
