If Republicans back down from this moment, the GOP will have lost all reason for existing. Reports are that Trump is going to nominate a replacement in the next few days. He will have done his part. Mitch McConnell has pledged that there will be a vote, though his language left it ambiguous if he meant before the election or just before the end of the year. All eyes are now on Mitt Romney, Lindsey Graham, Chuck Grassley, and others who have shown to be weak in the knees on this issue. They have a choice to make. They should choose wisely or there will be consequences.
