Using New Jersey as an example, Jeff Stein says that "higher taxes on the rich may be easier to campaign on than to enact" and the Twitter conversation is just about how this is just a normal feature of our (weird) democracy even when one party controls all branches. But the real issue is that Steve Sweeney is a corrupt conservative who runs as a Democrat because he knows that's what he needs to do to win in New Jersey (same as New York's IDC). Which i guess also may be a feature of our (weird) democracy, but i feel like that context is missing from the discussion.

Stein did good with counteracting Sweeney's obvious nonsense, for what it's worth:

A spokesman for Sweeney, the state Senate president, said families earning over $1.1 million in New Jersey already face an average $738 tax hike under the GOP law, citing data from the Institute on Taxation and Economic Policy (ITEP), a left-leaning think tank...

"It is not logical to consider provisions that raise taxes on the rich, while ignoring provisions that cut their taxes," said Steve Wamhoff, ITEP's director of federal tax policy, in an email.
