He'll always have supporters and sympathisers but I think the majority will slowly turn on him eventually, too. The QAnon in particular are a fickle cult who as of now believe he'll still be president and that smoking gun is about to arrive. Very shortly they'll realise it's not and they've been duped. A person admitting they've been scammed is painful and takes time... But eventually. It's what happens when you jump into bed with supremacists, evangelists, conspiracy theorists, far right etc only to become of no usefulness to them. America hates losers.He will still be remembered as a great leader by his supporters. The confederacy is still revered to this day.
Between that, the big tech companies pulling back, the Trump and Maga brands becoming toxic to fortune 500 companies, legal issues, financial complexities.
