I guess I just don't understand this sentiment.

Who out there will have their opinion of Trump change if they see him saying live that Russia should attack NATO countries? MAGA minds are wired to believe and accept everything Trump says as the gospel. Much like he said he'd lose no support if he shot someone dead in the street, he could actually start spouting lines out the playbook of the most progressive democrats and his poll numbers would not get worse, in fact they'd probably get better.

His performances and speeches DO speak for themselves, and that has been the issue for the last 8 years now. Trump simply was the successful candidate who tapped into where nearly half of the voters are, and instead of shrinking away when he said literally thousands of outrageous things, he leaned in. He was the first candidate in a long, long time to correctly read the mood of half the country.

This isn't a Trump problem. It is a "your neighbor" problem. Trump is what they want.
