Eh, if you think Markey's has more of a nuance policy on this, I want to hear your argument. I don't think he does, and I haven't seen otherwise.
Kennedy's answer is nuanced to the point it weakens his position. Maybe that makes more sense when you're crafting legislation, but we're at the point where people need to hear where you stand. Okay, he stand here, at the point where he's still okay with people still hurting. That's good information to have, and people should criticism him for it if they don't like it.
I personally don't like it, but like I said before, I don't have a dog in this fight mostly because it's not my state.
