There were two callers from heavy Republican districts in South Austin who called KLBJ to report that 1/2 of the machines were not working. This county is run by RATs, so that seems like the best place for voter suppression.
History has shown that heavily democratic areas do a worse job at electing officials that prepare for and execute elections competently.
However, this mainly makes it a bit more inconvenient to vote for some people. It does not prevent people from voting.
If having time to vote on election day is a problem for people, they should request an absentee ballot and vote that way.
There are plenty of options for voters. Laziness and procrastination is not an excuse.
I do have sympathy for those who attempt to vote and have it made more time consuming and difficult by incompetent elections officials. However, voting is important and is worth waiting or coming back later if necessary.
