One can oppose Romney while deploring the attack on Bain. I'd rather Gingrich and Santorum had attacked the left wing polices, by showing how they were much the same as Obama's policies, that Romney has implemented as a politician, not what he did as a businessman. Newt did that on Thursday. He should have done it before the NH primary, not when the "Bain" attacks backfired on him, and Santorum too.
Romney deserved being attacked as a crony, vulture capitalist. He practiced business without risk and targeted select companies for huge payoffs while pursuing a kinder, gentler more acceptable path with others.
IOW, a few slick deals with big rewards among a large number of innocuous deals.
That would be how such an operation would be run. It’s the same reason the Godfather ran an olive oil business. It provides cover.
