Former Sen. Pat Toomey's time in Congress, which began in 1999 after he won a House seat in eastern Pennsylvania, officially ended on January 3 when the new Senate session began.
Toomey was described in a 2004 New Yorker profile as "a conservative Republican of rigorous doctrinal purity: anti-abortion, anti-taxes, anti-spending (except for defense); a fiscal hawk, appalled by big deficits, a crusader for school choice, tort reform, Social Security privatization, and a smaller federal government." He's still that guy, but the Republican Party has changed—so Toomey declined to run for reelection this year.
