Moving goalposts? Since you didn't mention exactly what was moving goalposts I'll assume what you referenced. I do not think I specified any time when I repeated record voter suppression. When I did clarify, following what the news is talking about is the vote now.
I would expect YouTube to show more about voter suppression, from user produced content and not MSM content, during voting. Maybe a little about early voting, but I would expect the majority coming from voting day Nov 6.
Voter turnout must approach 100% to be proof that a record voter suppression claim is false. Turnout for presidential voting in 2008 was between %55.4 %64.0 for 18-24 and 25-44 respectively according to New York Times.
Given 1 million voters in a group, and we assume voter turnout is normally between %40 to %55 that gives 400,000 to 550,000 votes.
Assume maybe %8 were blocked from voting somehow, say purged from the voting rolls, that is 80,000.
Assume record voter suppression, maybe 150,000, so %15.
Assume record turnout at %84, so 840,000 votes cast.
Note that %84 + %15 is still below %100 of the electorate.
This concludes my PROOF that you can have record turnout (votes cast) and record suppression. Depending on the percentage claim of suppression, we can play with these numbers to see what sort of turnout proves the particular claim is false.
I will accept proof even if I do not like it. However, your claim that turnout is proof that voter suppression did not happen is incorrect.
