If they indict him, he will not be a viable candidate in 2024. If they leave him as is, then he splits the republican party and DeSantis doesn't have a chance of winning. If the republicans take Trump out of the mix, then DeSantis becomes a strong contender and possibly unites the party and wins in 2024.

Just a theory, but plausible. Personally, I think they should lock Trump up and throw away the key and then the Dem's should crow about being the law and order party. Unfortunately, the red part of this country isn't all that bright and would probably be corralled by Fox news into voting against their best interests as usual.
