How can the polls go from Hillary being 14 points ahead to

[INdemo]

just one point ahead nationally as per Washington Post poll in just two days?

[Foggyhill]

1. It can't, both are wrong

[Dem2]

3. Bad samples?

We'll see how it moves as days fall off the rolling average

4. 14 was too high

1 is too low.

[NoGoodNamesLeft]

6. The rates for Obamacare, likely

Which is why I kept saying she needed to put out an official statement on the issue. The pocketbooks of swing voters like myself is a HUGE deal. This stupid email thing with Comey is going to hurt too. I think Hillary will still win in the end, but it won't be a landslide like it would have been, so she gets no mandate and Trump spews election fraud and his minions get violent. Something needs to drop to destroy Trump.

7. Because the polls are bullshit

and have been a long time. One analysis is the polls are being rigged.

Another is that the corporate media are doing all this crap on purpose, because it helps them sell advertisements and get hits, and make money.

It stinks to high heaven.

8. These individual polls are the way to high blood pressure and ledge sitting.

I keep an eye on Nate Silver when this sort of stuff pops up.

And something on Politico is encouraging. Their polling shows that this new nonsense hasn't affected at least 63% of the likely voters polled.

9. Because polls aren't exact science.

10. They can't -- both are wrong

She will win by 5-7 points imo.

[Thrill]

11. Well one has been getting negative media coverage

For a whole week. And they been running Trump's lying speeches uninterrupted for a whole week.

12. about changes in who’s intending to vote. + 22 % shift of independentsto Trump in one week.

Changes in the poll’s latest four nights compared with the previous four are not mainly about people shifting in their candidate preference, but about changes in who’s intending to vote. Among those results in this poll, produced for ABC by Langer Research Associates:

As Trump’s controversies last week and the week before move farther into the rearview mirror, Republicans are expressing greater likelihood to participate: Eighty-one percent of registered Republicans now are likely voters, up from 75 percent a week ago.

In one example, there are 6 points more Republicans and GOP-leaning independents showing up in the ranks of non-college white women. This group was broadly for Trump a few weeks ago, then less so; it’s now back, favoring him by 59-29 percent.

Loosely affiliated or reluctant Clinton supporters look less likely to vote, perhaps given their sense she can win without them – a supposition that looks less reliable today.

Vote preferences also are part of the mix. At its lowest early this week, 82 percent of Republicans supported Trump. It’s 86 percent now. And his share of Republicans and GOP-leaning independents has gained 6 points, from 78 to 84 percent.

Trump, further, has gone from a 6-point deficit to a 16-point advantage among independents, with more Republican leaners in their ranks.

13. Voter intensity

Likely voters in that model a function of how excited they are.

14. Read their explanation: it is due to 1 question: Are you certain to vote?

It is almost all due to their likely voter screen. If they reported registered voters the change would be smaller.
