A tiny shift the other way could leave the Democrats with the Senate. This isn't over, not by a long shot.
One way of another, how will we be able to tell the difference between a Demonrat controlled Senate and a Ruling Class GOP-E controlled Senate? I suspect that the few differences are that elitist “Republicans” have better manners than Harry Reid (not a high mountain to climb nor a visible anthill) and care much more about the fate of Muffie’s trust fund. Maybe, watercress “sandwiches” will be served in the Senate Dining Room promptly at 4 PM each afternoon-—but no TEA.
