Mary Matalin - advisor to Dick Cheney - appeared on Meet the Press earlier today and refused to nail down exactly what "a beer" means in ounces, quantity, and/or alcohol content:
TIM RUSSERT: Was alcohol in any way, shape or form consumed during the afternoon? And should we accept the [Vice] president's "a beer" as literally one beer?
MARY MATALIN: What Katharine Armstrong was answering is a literal fact going to the question she was asked, which is always the case on the Armstrong ranch, you don't drink and hunt, and you don't hunt with drinkers. And that's what the sheriff reported, that's what she reported. It is true that the vice president had a beer at lunch, and let me ask anybody sitting at this table who knows the vice president, has known him for many years, has seen him in social situations, he's known not to be a drinker. But let me ask you a more logical question - you think the Secret Service would let the vice president out, tanked up, with a loaded gun, or let him be around anybody who's drunk with a loaded gun? It just defies common sense that the press would even go there. And that's why these adversarial question-and- answer periods set up the presumption that Cheney would be drunk, or having to deny that Cheney was drunk, as opposed to presuming what we all know, that he doesn't drink, he wouldn't hunt and drink, the Secret Service wouldn't let anybody around him who is drinking and hunting.
