2nd District Rep. Mike Simpson hasn't endorsed a candidate in the Republican primary for Idaho's 1st District congressional seat, spokeswoman Nikki Watts said today. "Mr. Ward asked Congressman Simpson if he could use his name on the event invitation for the event in D.C., and my boss said yes, and he would do the same for any other Republican running in the 1st CD," Watts said. "Primaries are very difficult, and so he just wants to support all of the Republicans. ... We're doing this and we'll do it for anybody else."
