Rep. Holden, Dean of Pa. House Members, Unseated.
U.S. Rep. Tim Holden, Pennsylvania's longest-serving congressman, lost his re-election bid in the Democratic primary, while Rep. Mark Critz beat fellow Democratic incumbent Rep. Jason Altmire in another contest that shook up the state's House delegation.
Newly-configured congressional district lines put in place by the Republican-controlled state Legislature affected the dynamics in each closely-watched race.
Holden, who was elected to Congress in 1992 and was one of its conservative, so-called Blue Dog Democrats, lost Tuesday to personal injury attorney Matt Cartwright, who spent nearly $400,000 in the race.
Asked to assess his victory, Cartwright said "It's a combination of things, number one, the redistricting, and number two, my own core political beliefs are a much better fit for the new district."
