U.S. Sen. Bob Casey Jr. did not miss a single floor vote during his first two years in office, putting him in a very exclusive club within one of the world's most exclusive clubs. Only seven senators made all 657 votes during 2007 and 2008, the two-year term of the 110th Congress.
"Public service is a privilege," Casey said in a statement.
Fellow senators on the attendance honor roll: Olympia Snowe (R.,Maine); Susan Collins (R., Maine); Herb Kohl and Russ Feingold (both D., Wisc.); Chuck Grassley (R., Iowa); and Ken Salazar (D., Colo.), designated last week as President-elect Obama's nominee for Secretary of the Interior.
