Poll: Trump within 1 of Clinton nationally

Donald Trump is within 1 point of Hillary Clinton nationally, according to the NBC News/SurveyMonkey Weekly Election Tracking poll.

Clinton has 46 percent support to Trump’s 45 percent, the poll found. Last week’s version of the poll showed Clinton up by 3 points.

{mosads}When Libertarian presidential nominee Gary Johnson and Green Party candidate Jill Stein are included, Trump leads, with 40 percent to Clinton’s 39 percent; Johnson has 10 percent support and Stein has 5 percent.

Only 11 percent of Republicans and Republican-leaning voters think the GOP is unified as the Republican National Convention prepares to officially nominate Trump for president. Half the party thinks it is divided now but will unite by November, and nearly 40 percent think the GOP will still be divided in November.

The poll also found that Bernie Sanders’s endorsement of Clinton did not have a large impact on most Democratic voters. Only about a quarter of Democratic voters said his endorsement makes them more likely to support Clinton, the party’s likely nominee, in November. Seventy-two percent said his endorsement didn’t make a difference.

Still, 44 percent of respondents think the Democratic Party is united now, up 13 points from last month’s version of the survey.

The NBC News/SurveyMonkey poll was conducted from July 11 to 17 among 9,436 adults who say they are registered to vote. The margin of error is 1.4 percentage points.

According to the RealClearPolitics average of polls, Clinton holds a 2.7-point lead over Trump, 43.8 percent to 41.1 percent. Several other recent polls have also shown a close race between the candidates.
