"The reapportionment of 2002 designed congressional districts that favored incumbents of both parties, leaving virtually no room for challengers to be elected. Of 435 members of the House of Representatives, only four incumbents lost to nonincumbents of the other party. In all, 96 percent of incumbents were re-elected. (It was only 90 percent in 1992 and 1982 after the previous reapportionments.)"
Wow man, that sucks.
