Really, that attempt was several steps down the line. First it was many attempts to overturn the election by convincing states to change their reported votes or just sending different electors. January 6th was the last-ditch attempt after those efforts failed.
I do recall Trump not wanting to let go of that power, in it? It wasn't out of his own magnanimity that he stepped down. Checks and balances still worked, appallingly sure, but they still worked.
I like how your literal argument is that Trump failed at becoming a dictator so he's obviously not one. Despite you know, demanding people find votes and organizing a riot.
A failed dictator is still a dictator. What's next, the events in South Korea weren't the result of a failed attempt at a coup?
