It's pretty clear that Barney's feeling his oats of late, what with the socialist in the Oval Orifice now. It's not enough that he can pack his own fudge in the privacy of his own home, he's got to carry the gay banner for all to see.
Unfortunately, Barney is a very smart guy. They love him in Masshole because they've been drinking the liberal Kool-Aid for so long that they can't wean themselves off of it.
With Ginsberg being the likely next justice to either retire or die on the bench, we might be okay for the four years that we've got to put up with the empty suit who'll be recommending her replacement.
Barney doesn't get it - the country as a whole (oops, don't get excited there, Barney, when I use the word "whole" or any of its homonyms) doesn't favor your gay agenda vis a vis marriage.
Do us all a favor, Barn, and just go smoke an appendage - and don't forget to wipe your chin.
