> I wonder what the top Republican leaders honestly think about these foreseeable outcomes
It doesn't matter what they think. Trump's message resonates with the electorate much more effectively than theirs, partly because of his political brand and partly because he has a network of social media acolytes who broadcast his messaging to each segment and demographic. It's a positive feedback loop wherein anyone who dares to go off-message or criticize his decisions gets instantaneous blowback from the MAGA audience themselves, so they quickly recalibrate. At this point, Trump has built a metaphorical tower of skulls of political foes within the party (e.g. Marjorie Taylor Greene).
They don't share Trump's message, or not exactly. They share an edited version of it. That seems to be why Trump has started insisting he's serious repeatedly. The conservative media is ignoring or toning down the least popular ideas.
It matters to me, because they were not powerless to stop this scenario. The point of a representative democracy.
After January 6th, Mitch McConnell could have whipped up the votes to impeach Trump. Forever banishing him from office. Or over the past four years, when asked, "Did Donald Trump lose the election" instead of equivocating, every Congressperson could have said, "Of course he did. Donald Trump is a loser who lost a fair election, but threw a tantrum when the result did not go his way."
Liz Cheney took a stand, and the party punished her for it. Trump was too popular, Republicans preferred to latch onto that energy, despite the consequences.
No raindrop thinks it is responsible for the flood. These leaders enabled this scenario, because they (correctly!) predicted it could help them hold onto power. Now we watch the results unfold as the world does everything to extricate itself from the USA.
Despite everything that has happened over the past year, the Democrats only have a few percentage points lead over the Republicans in current midterm polling. As an outside observer: Absolutely wild. I know a lot about the reasons, but it still feels completely surreal.
