It made it much harder for the usual Democrat holdout precincts to manufacture vote counts when everyone was watching the number of estimated votes left to count.
That is NYT you are referring to. If that fearure of their website is deemed inappropriate by the DNC it will not operate in 2020. And if it does continue it will be irrelevant. When vote counts exceed registered voters by large amounts there is NO blowback, NO consequence. The Republicans simply accept whatever number the Democrat vote counters provide, regardless of obvious divergence from real possibility. When the national average turnout is 60% of registered voters and a SocialDemocrat city reports a turnout of 120% the disparity is blatant, obvious, and accepted by all. Republicans truly believe the SocialDemocrats to be the natural rulers of the country and defer to SD arrangements and declarations as a matter of course. Republicans are happy that the SDs allow them to have some offices and their salaries and attendant opportunities to make lots of money on the side.
