There comes a point in haggling where even the best used car salesmen say, "Enough! Are you gonna buy this damn car or not?"

Now, with apologies to all hard-working used car salesmen out there, I'm comparing you to Democrats on this health care reform thing. Again, I'm sorry, but even you guys have to admit you see the similarities:

You're trying to close the deal. You've gone back and forth for hours, maybe days, maybe weeks and you've had it. Customers are getting antsy, closing time getting near, manager getting restless. You getting tired and now — nutty.

Democrats are now saying that the time for haggling over this thing is long gone — just sign the damn deal and be done with it. Forget about starting from scratch: Scratch this!

That's what happens when a big sale hangs in the balance: One side desperately wants to close it. The other, not nearly so desperate, could just as happily leave it.

But the Democratic salesmen on this have too much at stake. Yes, even if they know what they're pitching has too many holes to ignore. It still costs too much, and doesn't seem to do too much.

You used car guys know the feeling, don't you? Admit it. You get a little Jack Nicholson-ish, don't you? "Here's Johnny! Now buy the damn car!" And you start foaming at the mouth, spitting as you blurt out, "There's a line of guys right behind you who'd jump at this deal!" And you're standing now, sweating now, eyes bulging, teeth showing, beard stubble rubbing.

You're a bad "Pirates of the Caribbean" movie and you'd sooner have this bunion-head customer walk the plank than walk out that showroom door. Which is why Shiver-Me-Timbers Nancy and Harry and Captain Barack won't let anyone walk on this: The sale's too important.

Apparently more important than the customer for whom it was intended — if it ever really was.
