Poll shows Trump gaining on Clinton

Hillary Clinton and Donald Trump are separated by a narrow 3 points in a potential 2016 matchup, according to a new Washington Post-ABC News poll, with 46 percent of registered voters choosing Clinton to 43 percent picking Trump.

The picture is a bit different among the wider field of all adults, where Clinton has a significant 51-39 advantage.

The poll — 14 months from the general election — demonstrates the power of partisanship, which bring the less-popular Trump into a once-unthinkable position of nipping at Clinton's heels.
