Salt, for sure reps are not the only cheaters, however, when their political platform is based on being the "moral" party, having cheaters and even perverts that come to light makes them big fat hypocrites, and is a horrible reflection on the party as a whole, and on republicans and conservatives as a whole. That's probably not fair, but, its up to republicans to clean up their act (and their party).
If you are going to be the moral party, then you best act like you are.
