Trump won narrowly in Pennsylvania, which has a Democrat governor - and yet the Republicans hold a veto-proof majority in the legislature. Likewise, the PA congressional delegation is lopsidedly Republican. This is attributable to the fact that compact districts tend to produce lopsidedly Democrat districts in cities and - correspondingly - many more reasonably comfortable Republican districts. I would not expect a veto-proof Republican PA legislature to go out of its way to assure Democrat presidencies, which is what this scheme is obviously intends.A few years back the Republicans proposed to adopt the Nebraska Plan, and were dissuaded by a Democrat counterproposal for Voter ID - which was duly enacted, and duly invalidated in court, as the Democrats no doubt expected.
As I noted above, Republicans dominate the PA congressional delegation - and the Nebraska Plan would consistently have helped Republican presidential candidates in all elections between Reagan and Trump.
The distribution of Congressional seats in Pennsylvania seems remarkable similar to that in Georgia. There is a defacto alliance in the state legislature to draw up districts in which there are three safe districts for black Democrats and eight safe districts for white Republicans.
