One Senator notes the role of ethics rules in the atmosphere in Washington.  Senator Hatch explains:

“Both parties have become very polarized,” Mr. Hatch said. “A lot of that is because of the stupid ethics rules. We can’t get together at various events. A lot of people complain about taking foreign trips, which are really critical for us to understand foreign policy. The Internet is constantly badgering everybody. In the process, it’s gotten pretty doggone partisan, both ways. It’s bad.”
