Perhaps one more reason not to freak out? UPDATED (and yes, this is NBC/Surveymonkey)

at least not completely

Just out: NBC/SurveyMonkey nat'l tracking poll:2-WAYClinton 51Trump 444-WAYClinton 45Trump 40Johnson 10Stein 3Sept 19-25 +/-1.1% pic.twitter.com/CjUr5ocVkN

And yes the average of the national polls is still around 4%, basically the overall shape of the race over time.

UPDATE  okayl  story from NBC is here

2-way is a 7 point margin, 51-44

and here is Full Poll and methodology

a couple of quick snips from the story:

Trump's support among young voters remains consistent from last week. Likely voters under 30, however, have shifted support from Johnson to Clinton. Last week, 18 percent of likely voters under 30 supported Johnson. This week, 16 percent said they support him.

Clinton, on the other hand, went from 47 percent support among likely voters 18-29 years old to 49 percent support. Support among that group for Stein went from 8 percent last week to 7 percent this week.

In the four-way general election match-up, 49 percent of those under age 30 support Clinton, and 26 percent support Trump; 16 percent of 18-29 year old likely voters support Johnson, and 7 percent support Stein. Millennial voters support the third-party candidates more than older voters—only 5 percent of those 65 and over support Johnson and only 1 percent support Stein.
