The dude better known as Individual 1 is again an unindicted co-conspirator. In 2020, he is literally running for his life due to the statutes of limitations. If he loses, there is increasing chance to ends up in a orange jumpsuit unless the new prez pardons him. If Trump is smart, he resigns a few days before the end and makes a deal with Pence.
Why would Pence agree to that in exchange for being president for a few days/hours?
If Trump wanted to do that he should resign now, since that way it’s still in Pence’s interest Cos he’s got 20 months to run for re-election. If Trump loses in 2020 Pence would be better off not agreeing to any kind of pardon deal in the lame duck period since he’d be a front runner for the GOP nomination in 2024 anyway.
