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).
