“We owe him an open mind and the chance to lead,” said Democratic presidential candidate Hillary Clinton (C) at a concession speech, after being defeated by Republican presidential-elect Donald Trump —

WASHINGTON — A group of top Democratic Party strategists have used new data about last year’s presidential election to reach a startling conclusion about why Hillary Clinton lost. Now they just need to persuade the rest of the party they’re right.

Many Democrats have a shorthand explanation for Clinton’s defeat: Her base didn’t turn out, Donald Trump’s did and the difference was too much to overcome.

But new information shows that Clinton had a much bigger problem with voters who had supported President Barack Obama in 2012 but backed Trump four years later.

Those Obama-Trump voters effectively accounted for more than two-thirds of the reason Clinton lost, according to Matt Canter, a senior vice president of the Democratic political firm Global Strategy Group. In his group’s analysis, about 70 percent of Clinton’s failure to reach Obama’s vote total in 2012 was because she lost these voters.
