WASHINGTON, Oct. 5 (UPI) -- Former Vice President Al Gore will return to the campaign trail next week to stump for Hillary Clinton, targeting younger liberal voters concerned about his signature issue, climate change.
Polls show Clinton has struggled to win over some millennial voters who overwhelmingly backed her primary opponent, Vermont Sen. Bernie Sanders. A higher percentage of young voters than older ones are weighing a vote for either Libertarian Party nominee Gary Johnson or Green Party nominee Jill Stein.
