The attempts to fix this has come from the left. That the defenders of this are center/right do not suggest "both sides support" this.

Even in CA the legislature has done nothing to eliminate QI. That suggests it’s hardly opposed by the left.

People should stop treating California as the bastion of the Democrats, since it really isn't. There are 49 other states, many of them blue, that have none of the problems california has. California has been a state that struggles to govern for it's people since it was first created. It was a conservative stronghold for decades, and was no better under republicans. It seems more like there's something in the water, or rather that californian corporate interests have always been above the people there.

Conservatives scream about california because it's a useful red herring. California's stupidity is not limited to democrats, but conservatives really like to push that california is bad BECAUSE of democrats, the classic correlation causation thing.

Democrats often try to play the same dumb game with Texas, and that should be similarly rejected.

Not when courts twist themselves to pretzels to overturn or ignore those laws when they occasionally pass.

Also, only one party activists are trying to overturn it. Other part supports it. It is wrong to blame both sides.
