Did you read the article?
Sure did. Who do you imagine people in a Subreddit called r/The_Donald vote for? Alerting their membership to vote in polls and where they are is not brigading. But due to the sheer number of enthusiastic supporters it will have an effect - that is to show support for Donald Trump.
Washington Post will spin the article for Hillary and against Trump. They are partisan.
The reality is this debate was a wash. Hillary DID outperform and beat Trump but expectation was that she would win convincingly.... And she didn't. Her chance to show her strengths of policy and experience, and she could not do this well enough.
Expectation needs Hillary at around a 9/10 and Trump at around a 3/10. There was not much between them. Her at maybe 7.5/10 and he at about a 6/10.
The effect in polls will be negligible . She let a good opportunity go to waste. Next encounter both will have each other's measure. She unloaded most of her ammunition. She still has Trump University left to hit him with. Him? He has plenty. Clinton Foundation's pay for play including sell off of 20% of US uranium to Russian interests, her perjury in relation to her emails, Benghazi, Whitewater, Travelgate, the immigration exodus, cattlegate.....too much ammunition. He'll have to cram to get it all in. She has one more bullet left.
Trumps rise has had the effect of turning key battleground states red. Not previously safe blue states for Democrats, like Minnesota, Massachusetts and Illinois are not longer safe, but are being downgraded to "Leans Democrat". She needs to not JUST beat him but convincingly in the next two debates. Anything less will not check his rise.
Personally, I don't think she can do it. I think she is not evolving. I think she is what she is and will be. I think Trump adapts and is more than a little unpredictable. I think she may refine her technique slightly but then so will he. He will improve and their improvement will negate each other
