Crap like this gives me heartburn, it really does. I know it's totally irrational, but I need some better national polls from elsewhere to make me feel better about life.
I've been trying to assure my Trump supporting friends, now the a Clinton Presidency is pretty much a certainty, that everything will be ok. That this is much better for America. Headlines from the entire right-wing echo chamber that "Trump takes the lead!!" are not helping.
There are plenty of other national polls (from better pollsters) that should make you feel better.
As for the echo chamber, if this poll and the LA Times tracker didn't exist, they'd just focus on the online polls on Drudge, Brietbart, etc. You can't penetrate the echo chamber. I've got a Trump-supporting friend and colleague (a wonderful guy in most other respects) who looks only at those sites for his news. Occasionally he feels daring enough to venture to Fox News, but considers it too liberal and biased against Trump. I've tried to get him to at least look at some other sites, but for him they're all part of the media conspiracy.
