They know that the unanimous decision in Bush v. Gore means that they can huff and puff all they want, but in the end the legislature can appoint whatever slate of electors it wants, and with Republicans controlling both Houses of the PA legislature, they aren't going to be Hillary electors.
Liberal Federal judges can engage in sophistry, no doubt, but they don't do it to no purpose whatsoever.
we have a different Supreme Court than when bush v gore happened.
