Here’s your PQ: 57.2
Politicians with similar PQs are:
Olympia Snowe (R-Maine, 1979-2009) PQ=47.9
Arlen Specter (R-Penn., 1981-2008) PQ=50.6
Ben Nelson (D-Neb., 2001-09) PQ=55.6
Christopher Shays (R-Ct., 1987-2008) PQ=61.0
John F. Kennedy (D-Mass., 1947-60) PQ=63.7
The purpose of all this is to prove once and for all that the American media have a liberal bias. Which would be OK if the author were some hack, but for some reason that I can't even begin to fathom, he has a full professorship at UCLA in political science.
