The polls in Iowa have really been bi-modal. And naturally, PPP sides with the colleges that have ridiculous Hillary leads.
32-41 point leads:
PPP
Monmouth University
Loras College
3-11 point leads:
CBS/YouGov
Quinnipiac
Des Moines Register/Bloomberg/Selzer (rated A+ by 538)
NBC/WSJ/Marist
Gravis Marketing/One America News
You left out the fact that the first three are also the most recent. All the others were conducted before Biden's announcement/the Benghazi hearing, and the last two were even from before the debate.
Except for Gravis, none of these polls had Biden. The first 3 I mentioned are post-debate and no Biden.
And no, opinion didn't magically shift tens of points in Hillary's favor because of Benghazi. And she didn't gain any from Biden not running from polls that didn't have Biden. The post Biden not running and Benghazi hearing national IBD/TIPP poll with Hillary up 48-33 is the closest it's ever been in a poll without Biden.
Why do you keep citing the IBD/TIPP poll? They are not some gold standard pollster, they are rated average by fivethirtyeight and have a history of terrible results.
Bernard Sanders supporters have to follow their dear leader into the intellectually dishonest well he has made for them. Socialism? that's just government spending on hospitals and roads!!! Polls showing Shillary the Witch ahead? BIASED!!! The post-debate interweb polls showed Bernard winning because we voted a million times for him, please ignore scientific polls that showed Hillary winning.
This is the Anti-GMO crowd. Falling into their little rabbit hole will only cause you a life of pain.
