The only question is whether his actions around January 6th rise to the level of “insurrection”. He’ll claim telling his followers to match to the Capitol with instructions like "take back our country" and "fight like hell" was purely figurative, but given that there was no legal reason for them to even be there (the tallying isn’t a public survey, just officially recording what’s already happened) it’s hard to say his intention was anything but the illegal act it sounds like, and saying that wasn’t an attempted insurrection seems like you’re simply arguing that it doesn’t count if you are [fortunately] incompetent.
