Not all originalists will hold the same views on how to deal with ambiguity in the same way not all on the living constitution side agree how ambiguity should be resolved. The takes are usually more on the "how to think about resolving the meaning" side than a "is there any meaning to resolve" side.

That said, the originalist viewpoint is usually more along the lines of "we should seek to resolve that ambiguity in context of when, why, and with which references the framers who wrote it had in mind". Most originalists are unlikely to care what an argument about the current political environment implies.
