A nationwide USA TODAYSuffolk University Poll found both Clinton and Trump supporters are more motivated by fear about the other side claiming the White House than they are by excitement about their own candidate prevailing.br Clinton holds a 7-percentage-point lead over Trump, 48-41, close to the 6-point lead she held two months ago in the survey.br But the proportion of undecided voters is slipping, now below 10.br In a four-way ballot, support for third-party contenders has increased to 9 for Libertarian Gary Johnson and 4 for Jill Stein of the Green Party.br 80 of Trump supporters and 62 of Clinton supporters say if the other candidate wins in November, they would feel "scared," the most negative of four possible choices.br Those are stronger feelings than they express about a victory by their own candidate.br Just 27 of Clinton supporters and 29 of Trump supporters would feel "excited," the most positive choice.
