I am in Massachusetts. RCV was a ballot question. It lost. That means the voters didn’t want it. Overall, RCV is pushed by multiple members of the democratic party. So this idea that democrats don’t want it as some sort of secret party policy is wild.
Now, is it fucking dumb we didn’t vote RCV in MA? Absolutely. Most voters are actually fucking morons.
If it’s patented, you can just read the patent to know what else is in it.
