The one path he [McConnell] cannot allow the Senate to follow is to hold a trial in which the House sends over its prosecutors to blather about the president’s telephone call and quid pro quos for a few weeks, after which the Senate, entirely predictably, falls far short of the two-thirds vote needed to convict and remove. That way is all pain and no gain, except for endorsing the precedent of sham show trials.
There is a lot of this kind of talk around, and I can think of only one explanation for it: Trump’s partisans know he’s guilty.
