Moore is a pedophile, though. That is one of those more-or-less universally distasteful perversions. GOP seems to not give a shit about "normal sexual abuse and rape." As long as the two individuals are of age or within-same-age at the time, all is good.
Again, this isn't yet anything worse than who Clarence Thomas is, the Senate destroyed Anita Hill in the process, and so I just don't see this being much different...at least in terms of public opinion/GOP tolerance of this behavior.
Politically, the stakes feel much higher, so the difference, I think, will be stronger Democrat motivation to prevent another Thomas-like sexual deviant from being confirmed and further eroding the standards of the court.
