@coldjoint,
By the looks of it, Trump is losing the support of many top Republicans, or at the very least, they now acknowledge that Trump lost and Biden won.
It seems Trump mainly has the support of lower rank Republicans who don't have much pull within their own party, at least compared to McConnell’s heavy pull.
It is likely that McConnell is going to ensure that no Republican senator will object to the election results on 6 January.
