Republicans are edging closer to following through on a threat to “go nuclear” and blow up Senate rules to short-circuit a Democratic filibuster and easily seat Judge Neil Gorsuch on the Supreme Court.

As Senate Minority Leader Chuck Schumer, D-N.Y., continues to make his case for his colleagues to fall in line behind the filibuster to block Gorsuch from being confirmed, centrist Republicans who have a history of arguing to preserve Senate rules appear open to changing them if Democrats continue to try to obstruct his confirmation, as expected.
