What you say is true but Republicans do not generally manage to hang on to their Congressional seats when they get caught with their pants down. When Republicans have done similar things in the past, both Democrats and Republicans have demanded their resignations.

Weiner will probably survive this scandal. I would be shocked to see him resign.

David Vitter Senator from Louisiana, Republican, solicited prostitutes, a crime, and he still has his place in the Senate. Was not asked to resign.
Mark Sanford Repblican Governor of South Carolina was caught having an affair after running a campaign built around superior family morals. He was not asked to resign and finished his term.

Eric Cantor, the second highest Republican in the House, said we should pray for Sanford and Vitter's families and that it was up to the people if they should stay in office.
When he was asked about Weiner he said he should resign.
