Hatch the 'Busiest' Congressional Republican?

According to NBC's Ken Strickland, Sen. Orrin Hatch "is probably the busiest Republican in the Congress. Besides being a senior member of the Judiciary Committee questioning Sonia Sotomayor, he's also a key player in the health-care reform legislation moving through the Senate. Hatch is both a member of the Senate Finance Committee and the Health, Education, Labor, & Pensions (HELP) Committee. Both panels are tasked with writing the health-care bill. Additionally, he's also on the so-called 'gang of seven' which is a group drilling down on a bipartisan solution for health-care reform. (Hatch also serves on the Intelligence Committee, which has plenty on it's plate as well.)"
