That prediction is a non-starter, because you can bet McLame and Grahamnasty will side with Collins on saying "no" to the nuclear option.
Oh, I don't think so. The key will be for Gorsuch himself to meet with and impress McCain, Graham and Collins. Gorsuch's credentials are strong, and the quality of his jurisprudence will, in the end, unite the GOP.
Perhaps the solution is to invoke the nuclear option for Gorsuch, and then sunset it for the next SCOTUS candidate. For those of us able to see the positions of both sides, that seems reasonable - the opposition to Garland had everything to do with the reality that he would have replaced Scalia and altered the long-time balance of the Court. Gorsuch maintains that balance, so I'd think that even McCain, Collins and Graham would agree to invoke the nuclear option in his situation, so long as the minority's right to filibuster is maintained when the next Justice dies and must be replaced.
