My thought (which is worth exactly what you pay for it) is that we're going to have to get a solid "What firearms are protected?" case before the Supreme Court before Thomas and one or more of the other conservative members step down. The liberal, gun-grabber lawmakers are just going to keep turning the screws unless/until the SCOTUS finally steps in and says, "No!" If we lose one of two seats on the SCOTUS during a Democratic administration, we can kiss the 2A and the RKBA goodbye.
