What exactly does the term "voter suppression" mean?

Same here. However, last election we did have some trucks carting in ballots from New York in the middle of the night, and LOTS of dead voters.

Ballots found in trash bags on the street, and middle of the night shenanigans with observers being told the building is closing due to a flood, and then the Democrats pull out surprise...surprise...big boxes of votes from under a table with a tablecloth where they were hidden. All caught on the security cameras...(otherwise we would never know).

Mass ballot mailings to huge apartment buildings where the ballots were actually LEFT in the lobby unguarded, and absentee ballots mailed in by who knows who, without identification of any kind...NOT citizens.

When states like New York automatically register EVERYONE who applies for a drivers license to vote, that becomes a big problem.

Voting locations all actually have extended hours...no place will be closing early.

But if you have a drivers license, or a non-driver's ID card, you will have to show it now. NBD.

Every state is different which is why federal legislation is in order. Not everyone has photo ID and it's hard to get for some. The states that require it aren't doing so to address voter fraud. They're doing it to disenfranchise people.It's an absolute non-issue anyway. We've never had widespread voter fraud for any national election. It's a made up boogie man designed by the GOP to create an unlevel playing field. That's clear given their stance on the voting rights bill. They do not want to make it easier for people to vote.

It depends on who you ask, really.

Some people think it's a deliberate strategy to suppress votes while other people think its a fiction and that the people whining about it are counting on voter fraud.

Still others shake their heads and wonder how we got here.

Going out your way to make it more difficult for certain demographics to vote for political gain.

Voting districts have done many things that result in legitimate voters being unable to vote. The topic has been studied; the results are clear. "Voter ID laws have been estimated by the U.S. Government Accountability Office to reduce voter turnout by 2-3 percentage points, translating to tens of thousands of votes lost in a single state." https://www.aclu.org/news/civil-liberties/block-the-vote-voter-suppression-in-2020/
