Here is some interesting new information. We take it as a given that supporters and opponents of impeachment are basically locked into their positions. All the available evidence supports that conclusion. But there are small exceptions or nuances to that reality when you zoom in close.
There appears to be some disagreement between Senate Republicans and the White House on the length of a trial and calling witnesses. Senators just want to end things with a vote. Perhaps you’ll get a restatement of the case from both sides and then a vote. But it’s the same difference since we know what the arguments are. Little will come of that we don’t already know. There’s very little that is unpredictable or new. We have already seen over the last couple weeks that once we’re into pure partisan haggling, as opposed to unknowns and new facts, people tend to tune out.
