Let’s back up. It all started when Blitzer and Yellin were ‘riffing’ off of the stunning revelation that Barney Frank was on the front porch of his partner James Ready’s home in Maine when Ready was arrested for marijuana possession. Not being an “outdoorsman,” Frank dropped the bombshell of a claim that he did not see the marijuana plants in the backyard and wouldn’t have known what they were anyway. “Who knew that only outdoorsy types know a marijuana plant when they see it?” riffed Yellin.

Wolf Blitzer said he wouldn’t: but he’d know what one would smell like.

This comes in the wake of Blitzer’s non-response last year to the question of whether he had ever smoked marijuana: “you’re getting into a sensitive area,” he said at the time.

Dobbs went even further. When Blitzer lobbed him the softball question “you could smell marijuana, Lou, but you probably couldn’t recognize a plant. Am I right or wrong?” Dobbs responded by revealingly dropping the bombshell that Blitzer was “dead wrong” and he could do both “rather readily.”

It seems fairly certain that this dustup will cement Blitzer’s reputation as the ‘bad boy’ of cautious, middle-of-the-road prognostication and drive flocks of disaffected youths to CNN.
