If you are a Republican but don't approve of how the GOP majority has basically rolled over and abdicated its duty as a check on the president, remind your congresspeople that they owe loyalty to their constituents, not to other politicians. Taxpayers pay their salaries.
The Democratic party is also in desperate need of repairs if you are interested in direct political action. They have been self-destructing over the past couple of years, plagued by infighting, deer-in-the-headlights paralysis, political tone-deafness, and incompetence in messaging.
In addition, the increasingly authoritarian shift by the Federalist society ought to make room for a new counterpart promoting the rule of law. IANAL but have always wondered why the Federalist society had no similarly prominent opposing organization.
