Diesel, of the increasingly inaccurately-named Two Guys Who, Like, Never Agree, has what I must concede to be a more astute take:
It's facile to say that politicians simply enjoy grandstanding, though that not to say it isn't true. However, politicians often act in accordance with maximum utility in mind; they rarely continue doing things that don't play well with constituents (at least not publicly), because nothing is more important than the next election for most career politicians . . .
. . . The interweb cognoscenti has thrown up its hands and said that we're all tired of it, but obviously has miscalculated exactly who the "royal we" in this case represents. Leeches don't affix themselves to corpses, only bodies that still pump blood; the fact that the U.S. Congress is still involved indicates that the heart of the steroid issue is still pumping. Now, it's just a matter of figuring out why, and perhaps in the process discovering if maybe we're the ones who are missing something.
I suppose it's possible that it's only Henry Waxman who thinks this is important, but Diesel makes a good point in noting that almost all Congressional action is calculated, and someone in Washington has calculated that PEDs still has some legs.
