I heard a legal scholar say the other day, that they would still need a large majority in the senate to do that. I sure hope it is true, but nonetheless, monumental changes have occurred and are likely to continue.
Even if we can bring elections back to where they are near honest, it is likely that the bitterness will continue. Each election will have challenges, votes will be counted and recounted. Perhaps "impeachment hearings' will become the norm, etc. etc.
