Will less Republicans be voting or not?
Fewer Republicans will be voting than might otherwise have voted, as, among other factors, they too will have not received absentee ballots that they ordered.
But you knew that,
asshole. "Is this due only to the fact more Democrats were slated to vote absentee?"
You were also told about the fact that the pandemic is worse in the cities.
And you've also been told that members of your party take the issue less seriously on average; therefore they are more likely to go out to vote without giving a damn about potential consequences.
We'll see how badly suppressed the total vote is, but it should have been delayed. The failure of the system to get people's absentee ballots to them ought to have been reason enough to delay things. The risk to the public ought to have been reason enough to delay things. The need to shutter a huge majority of polling places in cities due to lack of workers should have been reason enough to delay things.
But your party is happier when there are fewer total voters.
