The following is a fact-check from the June 13, 2010 episode of Meet the Press:
ROGER SIMON (POLITICO) | In this election season only two of 217 house members lost their primaries – TRUE
MR. SIMON: That may be true, but it’s important to keep in mind that all but two of the 217 House members who ran for re-election won their primaries
According to both a CBS and ABC news article, out of 217 incumbents seeking new terms in the House, all but two have won their renomination. Therefore, we rate Roger Simon’s statement TRUE.
