This thread is not about whether or not government mailing ballots all over the place without being prompted is a good idea or not. I think it's not, but that's for another thread.
The parties of course are competing with each other. And realistically, there are only two parties that win any substantial number of elections. Fair play in all competitions is that rules are agreed on before the competition by the contestants.
That Democrats are ramming a new system down everyone's throats is in itself wrong and despotic. The parties should agree to changing the system of deciding who wins those competitions before the competition. One party should not be able to unilaterally change the rules themselves on their own.
Democrats keep saying we're a "democracy." Well, when one side is deciding how we determine the winner, it's not. Democrats are more and more like any despotic government that decides how elections will be run and who will win.
If mail in ballots are better, then we need to take the time and figure out how to make it work so both sides are comfortable.
So the question to address in the thread: Should one party be able to unilaterally be able to change the basic rules of the game over the objections of the other party?
I say no. Republicans should not be able to do it either
You have several flaws in your post. Nothing was jammed down anyone's throat. The fact is that the only reason that some Republicans like Trump oppse it is because the larger the turnout the more likely he is to lose. The Republican in Iowa who oversees elections sent out requests to every registered voter. The RNC is even pushing people to vote by mail. Making it easier to vote is not determining the election or despotic. You are the one who is a despot.
What you're doing is making the lame argument that if one Republican agreed to something anywhere then all Republicans agreed to it everywhere. Each State is different.
And you say flaw in my post, but nowhere honey did I say no mail in voting. In any state that wants to increase mail in voting, the parties should work together. And they will come up with different answers.
A Republican agreeing to something in Iowa is a Republican agreeing to something in Iowa. No less, but no more
That assumes the Republicans want to participate. In too ,any states, Republicans are the problem rather than the solution.
