Was part of that bad advice taking to the stage and claiming victory a few hours after the first votes had been counted? He had no reason to suspect election irregularity, all the prime news outlets were forecasting swings towards Biden once the mail in ballots were counted and that's what happened. Cue a whole load of petulant shouting of fraud that his lawyers shied away from once in court and the whole thing was a debacle. Chances are there were those giving him good advice which is to say that there wasn't any widespread fraud but was the man child going to listen to that? Of course not, his fragile ego wouldn't permit him to do the decent thing, concede with good grace and aid a smooth transition of power. Instead there's been a complete load of farce with Powell and her kraken, Giuliani hosting press conferences outside of adult book stores and My pillow guy ranting away like a lunatic promising earth shattering evidence of a stolen election that predictably came to nought.
You can claim that the OP is wrong all you want, doesn't make it so. In fact, after recent revelations he's looking more and more culpable.
