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.

Special thanks to crowd-sourcer Nanette for assisting with this fact-check.
