Beyond that, I have it on good authority that Obama tans, or at least has in the past.
This is entirely anecdotal, but a friend of mine used to work at this very posh health spa (as an interesting side note, she quit because she got her pinky finger severed in a door there, but that's entirely irrelevant to the story).
Anyway: several years ago, before he was president, even before he won the democratic convention, Obama came here to speak.
My friend was instructed to come in very early in the morning and open the spa, because Obama wanted to work out in privacy.
So she did, and he came in with a couple of other guys, worked out, and tanned.
She got to talk to him briefly, just small talk, and said he was very laid back and charming, very "normal".
But at any rate, he did tan while he was there.
So, clearly, the tax is not entirely aimed at whites.
* edit: just wanted to make it clear that I'm not referring to any sort of adult-oriented business here, or implying that Obama ever has or ever would patronize one. This was a legitimate health spa, with exercise and tanning facilities.
