They're Not Looking at the Same Thing as You
Trump's supporters aren't concerned about indictments, because everything is a conspiracy
Democratic and otherwise anti-trump political analysts have been beside themselves with frustration lately about how TFG's indictments have not moved the needle in polling in any meaningful way. Trump remains the frontrunner for the GOP nomination by a colossal margin. He shed a couple percentage points, most of which were picked up by Chris Christie, while Ron DeSantis is still working out how to articulate the line, "greetings, fellow humans!" into relatable, believable language.
But the reason Trump's support has barely wavered is because the adoration he gets from his strongest supporters is absolutely unshakeable. He is a messianic figure to them, and they have been conditioned to believe strongly that any criticism of Trump is borne of a deep hatred for America, and is therefore not reliable.
The belief in a "deep state" among Trump's base protects him from all potential criticism, and reinforces his infallibility to them. So when an analyst says something like, "how can these people still stand by him?" I say, "because they don't believe any of the allegations, and never will."
