Someone more familiar with the matter might correct me if wrong, but mail-in voting doesn't change a thing about "strange district boundaries." You still vote exactly where you earlier registered to vote, the same district boundary, just by mail.
He's not listening cause he doesn't want the facts and he's partially wrong again.
District boundaries can and were affected by those hoping to DROP OFF mail in ballots. Because
some republicans in power want to make the act of voting as difficult as possible for some, depending again, where they actually live!
Case in point, a state like Texas tried:
Texas counties will be allowed only one drop-off location for mail-in ballots, state Supreme Court rules
The court upheld Gov. Greg Abbott's authority under state law to limit ballot drop-off locations, issuing what is expected to be the final ruling in numerous lawsuits that challenged his order. As the coronavirus continued to endanger Texans, counties — often more populous, largely Democratic ones — began to look for ways to expand voting access in the fall election. Republicans have repeatedly challenged such expansions, like loosening Texas’ strict restrictions on who can vote by mail or allowing for drive-thru voting, in court. The Texas Supreme Court has kept Texas’ limitations on mail-in voting but allowed drive-thru voting in Harris County to continue.Now
maybe someone who Slobodan will listen to, will correct his misunderstanding about mail in ballots and the location voters live; it can indeed matter. If you happen to be a Democrat.
