“This is a once-in-a-lifetime chance to see a sitting vice president,”... sounds an awful lot like "Even a dog may look upon a king", which is a bullshit attitude for a republic.
He's a friggin' public employee, not someone of noble blood, 'seeing' him shouldn't be a big deal. We've given too much "This is SENATOR Foghorn" or "REPRESENTATIVE Kickback"; it ought to be "This is Mr. Foghorn, who's our Senator," something like that. Stop treating these politicians as if they're more than they actually are.
Can't remember where I first heard this line, actually a tv show years back, which I modified slightly: "Politicians are your employees. All too often incompetent or corrupt, but still your employees; and if you don't like how they work, you vote and you FIRE THEM."
