Force the constitutional convention that the right is advocating for ahead of their schedule and encourage peaceful mass assembly for the airing of various grievances. Institutional consensus has evaporated and the US is in dire need of an administrative and political reboot, so the choices are between doing that in an orderly way through the existing constitutional mechanism or waiting for it to just happen, which will be a lot messier.
Right wing political strategists have sought an article V convention for years, ostensibly to introduce a balanced budget amendment but in all likelihood with other strategic considerations in mind. The liberal left abhors the idea, both because of (wholly legitimate) suspicion at the origin and motivations of the proponents and (less creditably) because of basic conflict/risk aversion.
The right's national electoral strategy is to maintain power through the 2018 midterms (expanding it in a midterm election is historically rare) and control enough state legislatures by 2020 to trigger the convention, at which point all bets are off. I judge that they have a moderately good chance of succeeding with this strategy, not least because of superior political skills at procedural manipulation, but largely because of a smaller and more homogenous winning coalition.
Democrats and the left in general have been resisting this pull, but have lost the strategic initiative. They should, therefore, reverse course and seek to accelerate the process as rapidly as possible - because once the Convention is underway, procedural norms go out the window and power politics take their place. Employing the right's political momentum against them, within the scope of the existing constitutional framework, is by far the best strategic option. The alternative is at least a decade of political trench warfare, civil unrest, and international and institutional drift which could result in a catastrophic decline.
