Having been burned by their pollsters once before, I would hate to see Daily Kos' second pollster cooking their numbers, but that is the only answer I can see to explain some results in one of PPP's newest polls.
On May 10, 2012 PPP released a poll of Iowa primary voters testing possible Democratic and Republican contenders for the 2016 presidential race. The age crosstabs for the Democratic primary voters caught my eye. Follow past the jump to see why.
Can you spot the errors?
More young people can pick a candidate without Hillary and Biden then they could just without Hillary... Seems odd.
Also, Martin O'Malley's young supporters mysteriously jump ship if Hillary is removed from ballot, but re-emerge if Biden is removed as well... Hmm.
But that's just the start. Look at the percentages in the 18-29 column. 9%, 10%, 14%; these percentages could not all have occurred if the poll's sample size and age breakdown are anywhere near the numbers PPP gave.
If the Democratic survey included 335 respondents and 10% of these were age 18-29, being generous we should have a 18-29 year old sample size of 32 to 35 people.
If you look at my homemade Excel chart, a sample of 32 to 35 responses just cannot create the percentages shown in PPP's release. In fact, the lowest sample size that can produce results of 9%, 10% and 14% is 69, double the expected number.
What do you think?
