This was supposed to be the new – new! – Donald Trump, the more temperate Republican candidate who had emerged in the past two weeks seeking to broaden his appeal to a more diverse electorate. But with the presidential election just two-and-a-half months away, Americans seem decidedly unimpressed by this latest in a long series of tweaks, turns and transformations. The White House hopeful has been more disciplined in form, reading from prepared speeches and focusing his fire on his Democratic opponent Hillary Clinton, pounding away at the theme that donors to the Clinton Foundation charity were given special access to the then-secretary of state and her aides. And in terms of substance, he has polished his message, spending more time on the economy and reaching out to minority voters, particularly blacks and Hispanics.
