Jon Corzine shouldn’t be making fun of Chris Christie’s waistline; he should be hammering Christie on his corruption. Telling a company “I won’t prosecute you if you’ll give a million bucks to my alma mater” is solicitation of a bribe in my book. Too bad Corzine’s people think that personal insults work where serious charges won’t. I’m not saying they’re wrong, but it’s still a shame. And even though they’re right, it’s still the wrong thing to do.
