That is no different than on FR. Posters arrack other Republicans everyday here.
On DUmmies, I seldom see democrats attacking other Democrats . Some Republicans are cannibalistic. They love to eat their own. There are too many purist Republicans. It is their way or the highway.
No wonder democrats have been in majority longer since JFK.
I find two of your comments interesting.
First, “There are too many purist Republicans”. For decades we listened to the GOPe lie constantly to us to get elected and then tell us they couldn’t do what they said because they didn’t have the numbers or al of Congress or the Presidency. There was always a reason. Now there are some that are calling them on that and to say they are “purists” because they are taking a stand and calling them out on their lies is just another way of saying we need to keep accepting the lies and non actions. That may be acceptable to you but not to me.
Second: “No wonder democrats have been in majority longer since JFK” I won’t go into the cheating the democrats do that made a lot of that possible, but will address it from how the democrats operate. While they may be diverse in skin color, they are almost 100 percent in lock step in their ideology and present a united front. They don’t really have the differences of opinions that we see in the republicans. And when you stick together and defend regardless of idea or offense, then you often win. So, while you deride republicans here on FR and in Congress who are being purists, that is exactly what the democrats are and it has not hurt them as you point out. A perfect example of what I am saying is Trump’s first two years as president. He was almost completely undermined by, not democrats but two deep state Rinos, McConnel and Ryan. Those two represent the GOPe that lied to us for years, continue to do so, and continue to “compromise” which always seems to give the democrats what they want. So you can call it purist, but I call it fighting for principle and against the GOPe that has sold us out for decades.
