In a more hypothetical matchup, Democrat Bernie Sanders leads Trump by 15 points, 54 percent to 39 percent. The NBC/WSJ poll was conducted May 15-19 of 1,000 registered voters, including 450 cell phone-only respondents and another 46 reached on a cell but who also have a landline. Trump's rating is even worse than Clinton's: Twenty nine percent have a positive opinion of him, while 58 percent have a negative opinion (-29) — an improvement from his minus-41 score in April. Those numbers underscore Clinton's challenge in winning over Sanders voters once the Democratic primary contest concludes. Thirty four percent of registered voters have a positive opinion of Clinton, versus 54 percent who have a negative opinion (-20) — a slight uptick from her minus-24 score last month.
