Hillary Clinton's advantage over Donald Trump has narrowed to just three points, resulting in a dead-heat general-election contest with more than five months to go until November, according to results from a new national NBC News/Wall Street Journal poll.
The Democrat Clinton gets support from 46 percent of registered voters, while the Republican Trump gets 43 percent. In April, Clinton held an 11-point advantage over Trump, 50 percent to 39 percent, and had led him consistently by double digits since December.
In a more hypothetical matchup, Democrat Bernie Sanders leads Trump by 15 points, 54 percent to 39 percent.
The NBC/WSJ poll — conducted May 15-19 — comes after Trump has become the Republican Party's presumptive presidential nominee, but also as the ongoing Clinton-vs.-Sanders Democratic race has become more contentious in recent days.
