I caught part of Mark Levin's program Monday evening and I believe his position was the same as yours. If I understood him correctly, he said the only real remedy open to Gore would have been to contest the certification of Florida's electors, in which case congress would have voted. And given the composition of congress at the time, Bush would still have won. At least that's how I understood the part of his commentary that I was able to catch.
RE: #8, you are right. Also, he mentioned that Article 2, Section 1 of the Constitution gives the state legislature the authority to appoint electors as it chooses, and the FL legislature (majority Republican) was prepared to do just that, esp. given the kangaroo leftist Supreme Court in that state.
