If I were a teabagger, I wouldn’t be eager to accept that Romney is inevitable either. But he is inevitable, small groups of dead-enders notwithstanding. Perry was already dead before his latest embarrassment and he was the last chance. You can’t beat something with people who are either politically toxic, not really running for president, or both. I’m grateful to Jon Chait, who allowed me to not actually be the last person to figure this out, but it’s obvious. And when you have a scenario that uses the phrase “brokered convention” you really shouldn’t bother proceeding.
