Why does the left embrace gutter politics when a Rep. is immoral, but, ignore such discrepancies of their own?

I agree.I think there are men and women out there that would make excellent politicians but will not go into service for fear of things in there past.IT is not a right left issue,but a right wrong human issue.Its got ya politics that i am sick of when there are SO many other things seriously going on.We need leaders that actually lead!If politicians,from the Mayors up would just do there job,maybe we would not be in this mess!
