No, he's not capable of feeling shame.
Sen. David Vitter (R-LA) found an issue that he's getting a lot of attention for, and
he's not giving it up, even though it's really stupid and lots of his fellow Republicans hate it. The moment is passed for Vitter's effort to take health insurance away from Congressional staff, members and other federal government employees, but that's unlikely to keep him from continuing to pursue it as an amendment to any future legislation the Senate considers. So Senate Democrats are
trying to just get it over and done with, so far to no avail.
Senate Democrats have made an offer for Sen. David Vitter: You can have a vote on your health care amendment, but you have to live with the outcome.
The idea is to get the issue out of the way once and for all, so Vitter doesn’t continuously push for a vote on virtually every bill that comes to the floor, according to several people familiar with the matter. The Vitter plan—which would kill federal dollars to help pay for lawmakers’ and their aides’ Obamacare coverage—has become a major sticking point as the Louisiana Republican has demanded a vote ...
A Vitter aide said the senator will not agree to the request from Senate Democrats that he not bring up his amendment again during this Congress.
He's never going to get 60 votes for this and he knows it, so his only reason for refusing to agree with Democrats to have the vote and be done with it is just that: it would be done with. He wouldn't be able to gum up the works on other pieces of legislation by insisting on his amendment. He also persists in thinking that this bill somehow divides Democrats, that it's a politically difficult one for them. It's not. Which is why they are willing to have this stand-alone vote on it.
But Vitter just isn't smart enough to figure any of this out, so he's probably just going to keep plugging away with this dumb idea that everybody hates just to make life difficult for Senate Democrats who maybe want to get some stuff done. Because he can. Because he's part of the world's greatest deliberative body.
