WASHINGTON — Liane Golightly has finally decided who she’ll vote for on Election Day. Hillary Clinton is not a choice the 30-year-old Republican would have predicted, nor one that excites her. But the former supporter of Ohio Gov. John Kasich says it’s the only choice she can make.

“I kind of wish it were somebody else, somebody that I could really get behind 100 percent,” said Golightly, an educator from Monroe, Mich. She’s voting for Clinton, she said, only because she can’t stomach “childish” Donald Trump.

Like Golightly, many young voters are coming over to Clinton in the closing stretch of the 2016 campaign, according to a new GenForward poll of Americans 18 to 30.

Driving the shift are white voters, who were divided between the two candidates just a month ago and were more likely to support GOP nominee Mitt Romney than President Barack Obama in 2012.

In the new GenForward survey, Clinton leads among all young whites 35 percent to 22 percent, and by a 2-to-1 margin among those likely to vote.

The new poll also suggests enthusiasm for voting has recently increased among young African-Americans, 49 percent of whom say they will definitely vote in November after only 39 percent said so in September. Just over half of young whites say they will definitely vote.
