I read updates daily from the Bulwark, which is the mouthpiece of the "neverTrumper" Republicans. And I agree - while the opposition is vociferous, it's not clear what they achieve: as the OP says, it's as though they are all saying "oh, the Mid-Terms will sort it all out".
Trump as President does NOT have the power, constitutionally, to set tariffs all by himself. Yet we behave as though he does.
However I disagree respectfully with @Cossy for saying that Farage's "power and confidence appears to grow daily". I may be over optimistic but I feel that Farage's peak is approaching and may have even passed; for one thing Reform's modest capability to run the proverbial whelk-stall is being exposed in local government, and for another thing, Reform is being gradually uncloaked as a pro-Putin, pro-Trump party, and Farage trying to wriggle out in his various utterings does not change the fact that his top man in Wales has been convicted of serious treason, working for Putin. Kemi Badenoch has pointed this out now very forcefully and I hope she will continue to do so. She needs to get some clear blue water between the populist Reform and the traditional moderate Tories (the ones nobody ever hears from).
Reform are not "patriots". The thing with Farage is to notice what he does NOT say. So when Trump lays into Greenland and threatens tariffs against Europe (including us) Farage's line is "we don't like the tariffs" but he stops short of criticising Trump for his bizarre territorial ambitions or his naked desire to break up NATO (Putin is having a lovely week).
