Oh, Mitt, I wish it were that simple. No, the problem isn’t the lack of alternatives, it’s that your base is solidly under his spell and doesn’t want an alternative—they genuinely want him. Because he’s a strong man, and the rest of you are liberal-loving pussies.
Sorry, but your soil is salty. Doesn’t matter what crops you plant.
Yet, I support his quixotic effort, because an anti-Trump candidate in the primaries could land some punches that prove helpful to the (checks notes) non-Fascist, pro-(small "d")-democracy voting bloc in the general election.
