Mainstream media has been reporting that Trump is losing his grip on the Republican party - so much so that some outlets have labeled him a lame duck, prior to the midterm elections.
Nowadays, I take all such reporting with a huge grain of salt - because media outlets must make money - and are thus biased, at least unconsciously in their coverage. They - at the very least - do not cover stories unfavorable to their constituencies - and frequently exaggerate outcomes in favor of their audience's desires.
That said... numerous recent events indicate that Trump's heretofore ironclad grip on the Republican party is at least loosening.
To wit...
Some MAGA politicians are either in outright revolt against Trump (e.g., MTG) or are resigning from office;
Republicans in "purple" districts went against Trump and Mike Johnson and voted for an extension to the ACA;
Trump has been forced to back down on his efforts to prevent disclosure of the Epstein files (I suspect that he'll continue in this vein claiming that ongoing "investigations" preclude disclosure of all files);
MAGA is skeptical of Trump's undeclared war against Venezuela;
And other such indications exist too which I can't recollect ATM but I'll bet that you can.
This brings a lot of hope - for me - in the possibility that Democracy will prevail in 2026. For 100% sure Trump is going to do whatever he can to steal the midterm elections by any means necessary - but recent events bring hope - that officials, both Republican and Democrat - will do the right thing in 2026 - and that fair and free elections will occur. And if in fact elections are fair and free in 2026 - there's no way in hell that Republicans retain control of the House - and it's even possible that they'll lose the Senate too.
