Sorry, it is entirely rational to see the difference between consulting, a form of capitalism, though the client was a government entity, and manipulating capital, loans, and debt to glean profit off a dying business by
way of GOVERNMENT regulation in bankruptcy code, which from what I have read, is essentially what Romney did in some cases at Bain. If it hadn't been for government, that particular form of "capitalism" would have failed.
Gingrich is very flawed, but he measures up to Reagan's "good enough if he agrees with you 75 or 80 percent of the time." THAT is what's called "rational," while attacking him to defend an opponent who barely meets 10 percent, is INSANE.
Making the perfect the enemy of the good is irrational.
