As a number of Republican Party leaders express dissatisfaction with Donald Trump being their party’s presumptive nominee, rank-and-file Republicans have become more positive about the billionaire businessman. Over the last seven days, Trump’s favorable rating among Republicans and Republican-leaning independents has reached 66%, the highest since Gallup began tracking him nine months ago. His unfavorable rating is at 30%. …

Trump’s image among Republicans, however, is still significantly more negative than that of the last three Republican nominees at about this point in their presidential campaigns. Mitt Romney, John McCain and George W. Bush had coalesced their party’s support into a more universally positive image by May or early June of 2012, 2008 and 2000, respectively, with favorable ratings in the 80% range and low unfavorable ratings.
