We’re early in the formation of a grand coalition in opposition to Trump, but however long the task, that effort should focus on the top: Trump, his inner circle, principal surrogates, and media defenders. All in all, that’s a small group on which one may concentrate.
There will be endless tactical debates about how to reach this voter or that one, to shrink Trump’s room to maneuver here or there. These discussions will be well-meaning (as they’ll be directed at Trump’s political ruin), but they shouldn’t be our principal focus.
A focus on Trump, key aides, and those who defend him in the media will accomplish three things: (1) assign responsibility where it is most deserved, (2) allow concentration of resources, and (3) speed a separation of Trump from ordinary people who are mere marks in his long confidence game.
Blaming those he’s conned is a sideshow. (There’s a necessary exception for the very few who are of the alt-right; they deserve, in-and-of-themselves, obloquy whenever one has the time.)
If Trump breaks politically, it will come from the case against him, and his present supporters will by turns break away (or in any event will have nothing left to support). In this way, his remaining supporters won’t be able to support him adequately in the end. He’ll stand or stumble despite them.
If Trump should meet his ruin (and he will), it will come from a relentless case against his mediocrity, lies, bigotry, character disorders, and authoritarianism. One needn’t ask why people support him now; it’s enough to show him again and again as unworthy of support.
Now, there are alliances to build, and a case to make, against Trump and those in his circle.
