You'd think that the blatantness of this all gave the game away. It's possible that there is no way they can actually accomplish this (I hope -- it'd be much scarier if they could), but did it anyway to make a useful cultural statement.
The correct and maybe only real recourse is to vote these people out of office. This is the State Senate and the State Legislature there. It's not just the national elections that matter, and it's one reason why the remarkable year Democrats have had at the state level in special elections, etc, is noteworthy.
