I beg to differ on the point of trump's criminality and the likelihood of his being in jail.
JAIL is where donald OUGHT to be by the time the '24 election rolls around.
If Chris can maintain a public persona of effectively and pugnaciously opposing trump, then Chris will have served his primary purpose in joining the pack against the chief traitor.
Then when trump goes down in the Justice system and finds himself safely incarcerated in a federal prison, Republicans can turn their attention to any other actual statesman, or stateswoman. At that point in time it is likely that Chris will have completed his combative role in returning the party of Lincoln to its roots.
