But like it or not, even their unconscious, comatose, near death bodies would still count as members of the Senate, and give the conservatives in the Republican caucus control of the committees and the floor. That is their only value.
The same is true of the RATs, except they would actually bring them in from the nursing home or ICU to cast an important vote.
Own it. You defend liberal republicans. You defended Romney.
You don't get to tell other people what to do. You might convince them, maybe, but not with a don't vote for that liberal he's a Dem, vote for this liberal, he's a Pub.
I have no use for illiterate, un-educated control freaks.
