On a plate or on your face, its tasty!
Look, everyone around here takes presidential politics as serious (or in my case entertaining) business. You should be happy there are good people who do that. I don't know about you people, but in my daily life I meet very few people who give a damn about politics at all. They just vote their party every four years and forget about it, if that much. I know quite more than a handful who won't even do that much, even with prodding. They just don't care.
So stop being schoolmarmy about the rough and tumble of a Democratic presidential primary. We've got good candidates (even though they're old). We should enjoy a nice fight over things both important and trivial. Be thankful you've got knowledgeable people to spar with. Even when it gets nasty, enjoy yourself. You'll get your share of HRs, some fair, some not. Have a beverage and live with it.
Pie fights dont kill anybody. Pie is rather tasty actually. Even when you've been hit in the face with one.
