The 3 worst are registered voters.
Reuters/Ipsos was the one that changed to more favor Hillary.
NBC is an online poll of registered voters
Economist tracks from 8/14-16.
LA Times from 8/10-16.
The RCP Average is somewhat encouraging, because it shows an upward trend for Trump and the gap narrowing.
RCP is not the sole source for polling data, either.
But it’s foolish to ignore the bad news, and so far RCP shows improving, but still bad, news.
