Simpson has represented the district since 1998
Thirteen-term Rep. Mike Simpson, R-Idaho, won the Republican primary in his re-election effort for Idaho's 2nd Congressional District.

The Republican has represented the Gem State in Congress for 13 consecutive terms, advancing Tuesday night to face Idaho Falls Democrat David Roth, who is unopposed, in the general election in November.
