Bullshit. Somehow, those bastions of ignorant red of Texas and Florida manage to have their mail in ballots counted before Election Day for posting that night. Why you ask? Because their legislatures approved it. If you want to know why it takes so long to count mail in votes in other states, please see the largely Republican legislatures who make those rules.
I get it like in Pennsylvania where a republican legislature { as in all
state legislatures } decides how their State managed Elections.
The Drat Governor {Tom Wolf } and his Trump-hating Secrtetary-of-State
{ Kathy Boockvar } in the last couple days before the General Election
tweeked { changed } firm State legislature guidelines for how mail-in
ballots are received and Verified.The date they must be in by to be
counted.Normally by 5 pm on Election day.
They also extended that time frame for up to 3 days after 5 pm
on Election day.
The Pennsylvania State Supreme Court { majority of Democrats }
overruled the Majority Republican legislature for this tweeking
exibition.Back in October Judge Alito tried to have his Supreme Court
hear the case as to these kinds of last minute Election changes but
Chief Justice Robers blew it off.Wouldn't even consider.
