Your point can be turned around - - where are the conservatives who had a problem with Clinton, even with his antics as far back as the 70s? Arnold's candidacy is making them feel comfortable with depravity - - - - that's why I say it's exercising a degrading influence on the party. Having a GOP governor of the largest state be a pro-abort, pro-gay-adoption liberal is going to undermine the party as a voice for social standards, but I guess you don't care about that?
Bill Clinton turned the Oval Office into a bordello. His history included allegations of violent rape and serial sexual harassment. His sexual harassment of innocent female vistims continued in the White House. The Oval Office became known as the "Oral Office." Clinton's conduct changed the sexual behavior of a generation: How many young teenage girls today now wear tongue studs and lip rings as a way to openly declare their "specialties" and oral talents?
Arnold's adventures over twenty years ago do not even come close to reaching Clinton's degenerate moral depravity.
Clinton's antics as far back as the 70's involved several credible and identified accounts of extramarital affairs, sexual harassment, and at least one rape. To date all you've shown for Arnold is him telling a single lewd story 30 years ago that very likely never even happened. It's just plain silly to pursue. You might as well be attacking adults today for telling dirty jokes when they were in high school.
