Roberts is no longer the Swinger Vote.
That role apparently belongs to Kavenaugh, hand picked by Kennedy to replace Kennedy.
Roberts, Kavanaugh, and Gorsuch are all swing votes.
I've said it before and I'll say it again: we have an equally divided 3-3-3 court... 3 rock solid conservatives, 3 hard core communists, and 3 right-of-center squishes who can defect to the RATS on any given case.
