John Fund: “For a party that prides itself on promoting business-friendly policies, the Republican party failed to perform the basic due diligence anyone in the private sector would have demanded before hiring someone for a CEO position. In doing that, Republicans ended up not with a leader but with a giant distraction for a nominee. Because GOP voter turnout could be depressed as a result, Republican control of the Senate and even possibly the House is possible. By taking Donald Trump at this word that he had nothing to hide, too many Republican leaders may find they have everything to lose.”
