No, no I didn't.
In the end I don't think the analogy works very well when you factor in the fact that Santa isn't on my payroll and my local congressman is. One of them works for me and the other's a chubby elvish freelancer. (Both like milk and cookies.)
But, for the sake of argument, let's run with the analogy. Let's say you wrote a letter to Santa reminding him that you've been a good little boy or girl and listing out some of the things that might make good gifts, if he was in the mood. At the top of the list you put the things you really, really wanted like a shiny red bike or that Malibu Barbie you've had your eye on. At the bottom of your list was things like baseball cards or school supplies.
Now let's say Santa skipped everything else on the list including the bike with the only gift you had under the tree on Christmas morning was school supplies. It'd be hard not to be disappointed, no? Especially when your elephantine brother who constantly misbehaves gets everything he wants.
You'd find yourself asking what the point is of being good in the first place? You'd start to wonder if there was any justice in the world. You'd probably find yourself getting to the place where you had no use for Santa since he doesn't listen anyway.
You'd ultimately wind up voting Santa's sorry ass out of office the first chance you got since he was an ungrateful son-of-a-bitch who doesn't give a rat's ass about people like you who leave cheap cookies rather than the gourmet cookies he enjoys.
