It's good politics, because the majority of voters believe the Supreme Court is out of control, but this will never pass Congress.
It's part of the strategy.
"Look at what we are trying to do for you and look at who is trying to stop it. We care about improving your lives, they only care about improving theirs."
They'll have hard evidence.
We tried to do X and they blocked it.
We tried to do Y and they blocked it.
We tried to do Z and they blocked it.
We know these are the things you want because you said so in so many polls and with your vote when you voted for our platform. Look who cares more about themselves than America.
We offer you the things you want. They offer you nothing, in fact they offer you less than nothing. They want to take what little is left while cutting taxes on people who make more money every year than you and five of your neighbors combined.
If election day is a federal holiday
If felons were allowed to vote(seeing as apparently one can run for office)
If gerrymandering was made illegal
If there were term limits for all elected and appointed positions.
You will have killed the republican party and forced it to turn into a party that actually has to win people over with legitimate policies instead of just appealing to prejudice. They have no plan for climate change even as natural disasters wipe away lives and property. They have no plan for housing even as businesses buy up the little affordable housing left and jack up the price. They have no plan for increasing access to medication and doctors. They have no plan for addressing the population decline. They have no plan for bringing jobs back to America while China continues to invest in its own manufacturing and businesses which will compete aggressively. They have nothing other than a promise to make life harder for other people that don't even have the power to affect others standard of living.
