Democrats have been in majority much more often because they NEVER EAT THEIR OWN. If someone posts a single post on DUmmies denigrating ANY democrats, the post is immediately removed and repeat offenders are zotted. Republicans behave like cannibals, eating their own. No wonder they are usually a pitiful minority in power.
Unfortunately, most GOPeers are not.
SAD.
They aren't eating their own they are purging traitors. It may not be true but I have heard that sometimes soldiers dress in the enemies uniform to cause trouble in the ranks. Just sayin, may not be true.
