Mitch McConnell told his leadership team in private this week what’s becoming increasingly obvious on Capitol Hill: Supreme Court nominee Neil Gorsuch probably won’t get 60 votes to avoid a filibuster.But the Senate majority leader had an equally pressing message: Republicans should have no compunction about pulling the trigger on the “nuclear option” — with Democrats resisting a high court nominee as well-pedigreed as Gorsuch.“Feel no guilt,” McConnell said, according to attendees.McConnell’s attempt to buck up his GOP ranks, relayed by three sources in attendance, underscores the high stakes of the Gorsuch battle as the Senate barrels toward a likely nuclear showdown next week: His confirmation is, to put it mildly, a can’t-lose for Republicans.That was true after Senate Republicans waged a yearlong blockade of Merrick Garland that positioned the GOP to pick someone else now.
