McConnell is quite willing to let the Democrats focus on impeachment and Trump, thus relegating the inauguration of Biden to a sideshow. He is happy to give the Democrats enough leash to play rope-a-dope with themselves. Impeachment will supplant and delay Biden nominations and Biden’s legislative agenda. It will obscure whatever Biden is doing about Covid. Impeachment is also very divisive and can rally the Republican base. Impeachment when there are less than a few days left in Trump’s term makes no sense to Independents. McConnell understands that when your opponent is skating over to thin ice, there is no sense in trying to stop them. Democrat leaders may have to give McConnell something to publicly oppose Impeachment so they have a reason to stop hitting themselves over the head.
