A week ago, I suggested that—contrary to conventional wisdom and perhaps even to first-blush common sense—the GOP field might benefit from one or more new candidates. One of the well-qualified dark horses I mentioned was third-term Rep. Mike Pompeo from Wichita, Kansas.

Pompeo’s been a leader in fighting the Iran deal, and has kept on battling over this recess. Recently he criticized a former Kansas Democratic congressman, Jim Slattery, who’s been campaigning for the deal and (following President Obama’s lead) slandering its opponents. Pompeo put out a release that got good coverage in the local papers. It would be nice if lots of other Republicans were as aggressive in making the case against the deal—and in turning up the heat on its defenders.
