Read the article again. Each of the states have laws about electors stating that they should be designated by popular vote. There is nothing at the federal level that requires such. The issue is that the plan (as relayed by many republican sources) is to raise as many legal challenges as possible to the accuracy of the vote. Then, push the challenges out until the count has to be certified and electors have to be verified (Dec. 8). Then, have the republican legislatures in the states say they clearly saw the election fraud and that the "valid" votes clearly show a republican advantage and validate republican electors. Since there is no certified county, it would be very difficult to challenge to the Supreme Court. Yes, if they are able to pull it off, it would be the final stage to a banana republic. One thing that the article got wrong is that if it does go to Congress, The House picks the president, but each state gets one vote. Right now, most of those states have more republican representatives (partially thanks to gerrymandering). That may change in the election and it would be the new Congress that choses the President and VP.
