There might be some disputation over whether the Donald Trump-Republican Party unholy alliance is politically effective in terms of the consolidation of executive power or actual legislative activity–seasoned political observers consider the Trump administration to have been an utter failure on both fronts–but there can be little doubt about the extent of the damage the combination of the Trump administration and the Republican Party have done to American political institutions. They have done so in two ways: first, they have systematically captured components of the electoral and legislative process, exploiting their structural weaknesses and their dependence on good-willed political actors (which the Republicans most certainly aren’t); second, they have engaged in a wholesale rhetorical condemnation and ridicule of central and peripheral political institutions like the judiciary and the press.
In the former domain, we find a bag of dirty tricks that includes gerrymandering of state electoral districts, wholly fraudulent investigations into voter fraud, repression of voter registration, filibusters, supermajority requirements to call bills to vote on the floor, the stunning refusal to vote on a Supreme Court nominee following the death of Antonin Scalia, and so on. In the latter domain, we find the ceaseless vilification of judges who do not align their votes in the ideological dimensions preferred by Trump, an utter disregard for all manner of ethical proprieties (c.f. the absence of any sensitivity to the non-stop conflicts of interest that are this administration’s trademark political maneuver), and a wholesale rejection of any standards of truth or evidence in the making of substantive factual political claims.
The American polity will be rid of the Trump administration via resignation or electoral rejection soon enough; perhaps it will even remove the Republican Party from power from all three branches of government. It will not, however, be rid of the damage caused to its political institutions any time soon; it will take a long time to for this damnable stain to be removed, if at all. Cynicism about political institutions and practices is as American as various species of fruit pies; it is the natural result of a systematic effort by the political class to bring about widespread disengagement with national and state-level political processes, thus clearing the field for those seeking greater control over them. That effort has been spectacularly successful over the years; low voter turnout is its most visible indicator. The efforts of this administration and the Republican Party, aided and abetted, it must be said, by the Democratic Party, have pushed that cynicism still further, into realms where the abdication of political responsibility and the loud proclamation of moral bankruptcy has come to seem a political and intellectual virtue. So overt has the abuse of the political system been that a collective weariness with politics has prompted an ongoing and continuing abandonment of the field; better to walk away from this cesspool than to risk further contamination. That abandonment clears the way for further capture and degradation, of course; precisely the effect intended (see above.)

Yes but the only answer is for more people to get positive about US politics, and move for change in the right direction.
Indeed, the only way forward is increased registration and turnout and education.
