With 23 weeks until Election Day, Donald Trump — the unlikeliest, most unconventional nominee of a major party in modern times — faces two challenges.

The first is to rally the 30 percent of the GOP faithful who remain at least reluctant to rally to his banner; the second is to lower his unfavorable ratings among the general electorate. (Gallup’s numbers from last week led the polling giant to remark that “Trump has a significantly more negative image than has been the norm for his party’s nominees at this point in recent campaigns,” and that the “relative lack of enthusiasm for Trump among his own party may not be his biggest challenge to winning the presidency — twice as many Americans overall have an unfavorable (60 percent) as a favorable (34 percent) opinion of him.”).
