Its not about being gentlemanly anymore - the implications are too obvious.
Hatch and friends are no longer fit to represent those who put them in office.
But it is. And it's precisely why the Republican senators are still acting like they are. They're convinced, STILL, that if they still play their part in the House of Lords called the Senate then the Dimwits will treat them right. Of course the Dimwits are playing hardball and far to few of the Republicans have realized that yet.
