Republicans are going to vote Republican. I know they are trying to overthrow the Supreme Court. I know they are trying to overthrow Constitutional rights. I know they want to install a fascist dictatorship. So yes, absolutely they are to blame for INSTALLING these Supremes, and the current state of lost Constitutional rights. And if they vote for Trump again, they are straight up Neo-Nazi Fascists.
BUT: The only way to stop them is to vote Democrat. A Republican may be to blame for ELECTING to put those people on the SC... but the only way to STOP that is to OUTVOTE them and get a Democrat in place instead.
For NOT voting enough for a Democrat?
In order to defeat the Republicans who are going to put Alito, Gorsuch, Kavanaugh, Coney-Barrett and Roberts in place?
Why would I blame Republicans? They're going to vote Republican.
The only way to stop them is to vote Democrat.
So if the Dems, in 2016, 2022, 2000, or in any other year decide to sit at home and put up 64MM votes instead of the 81MM votes plus that they COULD have put up... Then they DO deserve a portion of that blame. They are NOT blameless.
