Franken needs to just resign and allow the Republicans to seat Moore. The Democrats take the moral high ground and the GOP will be the party of embracing pedophiles so they can pass tax cuts.
Moore will be investigated, if he wins. He will likely swear under oath the entire yearbook notation is false. If it is, he survives. If it is all true, he is dead meat. If it is partly true, he is probably dead meat.
If he were expelled, it would be for lying under oath.
The question is did Gloria throw Moore a lifeline.
