Tell your politico it isn’t Rubio who’s going to spill the blood.
Crist can decide what he wants to do. But voters don’t particularly care about candidates’ personal self-actualization projects, nor are they or the Republic well-served by such narcissism.
If there’s blood, it will be because of Crist’s selfishness, not Rubio’s decision not to wait in the wings.
