Pence is not a strong candidate, so it's unlikely the Republicans would risk running him in 2024. The beauty of the Larry Levine plan is Pence gets to appoint a new Vice President, probably a popular up and coming Republican congressman who can then claim experience to make a Run for President in 2024 as a former Vice President.
Trump gets to act as a kingmaker! He will love that!
Then they run one of Trump's kids as the VP running mate in 2024! Probably Ivanka so they can throw a woman against Kamala Harris.
A neat little package. The Republicans get a bunch of pardons and position themselves for future operations. Trump won't wanna resign but he needs the pardon. Just my opinion on how I'd handle it to turn a loss into a future win!
