Daily Kos readers contributed more to Colorado recalls than NRA. PPP admits it purposely didn't release a poll showing likely Colorado recall result, earns Nate Silver chide

"Supporters of the incumbents spent over $3 Million (mostly coming from out-of-state special interests) while supporters of the Recall spent nearly $500,000."...

"The reason, according to PPP pollster Tom Jensen, was that “in a district that Barack Obama won by almost 20 points, I figured there was no way that could be right and made a rare decision not to release the poll.”"
 
9/11/13, "PPP sat on poll showing Colorado recall strength," Legal Insurrection, William A. Jacobson

"PPP has admitted that it deliberately did not release a poll showing that Colorado State Senator Angela Giron was likely to lose the recall election by a wide margin....

PPP is the pollster for Daily Kos, whose readership invested heavily in the recall elections, contributing more money than the NRA....

This strikes me, however, as a no-win for PPP.  A good argument can be made that by keeping Giron’s weakness a secret, it disadvantaged left-wing groups like Kos who might have gone into panic and GOTV efforts more intensively had they known.  If I were Markos, I’d be upset, even if Kos did not commission the poll.

I’ll chalk it up to a bad decision, until further information demonstrates otherwise.

Update:

"Nate Silver        ✔ @fivethirtyeight
 

VERY bad and unscientific practice for @ppppolls to suppress a polling result they didn't believe/didn't like. http://www.publicpolicypolling.com/main/2013/09/reflecting-on-the-colorado-recalls.html …""

9/11/13, "PPP admits hiding Colorado recall poll," Washington Examiner, A. Schow

"A spokesman for Public Policy Polling admitted Wednesday to withholding a poll showing Colorado voters were going to recall State Sen. Angela Giron by a 12-point margin.

The reason, according to PPP pollster Tom Jensen, was that “in a district that Barack Obama won by almost 20 points, I figured there was no way that could be right and made a rare decision not to release the poll.”

When the votes were counted in race, the poll turned out to be on target, as Giron lost by 12 points. “We should have had more faith in our numbers,” Jensen said."...
