PPP under fire from Cohn, Silver, etc.

Um, no. He didn't attack their methodology. Learn to read.

Silver's right. He's not challenging PPP's accuracy like those poll re-weighting morons or calling them discredited. He's just pointing out that yes disregarding a poll you conduct because you don't like the results is not scientific or correct. And worse of all this will just fill ammo for the critics, every PPP poll will get dismissed by right wing trolls in 2014 with this being the grounds (and perhaps ironically Silver's model as well due its inclusion of PPP.)

Cohn's criticism of the methodology is a bit more open to attack since yeah PPP is accurate despite all that. But I don't see anything wrong with criticizing PPP for this as it doesn't involve their accuracy.

Once again Silver is not criticizing PPP for their methodology. He's criticizing them for an action not too far off from what the poll reweighting idiots were doing last year, or J. J.'s Bradley Effect blather and Phil insisting we not listen to the polls and instead listen to his reports of who people told him they were voting for in 2008.

PPP arbitrarily tossed a poll because they didn't think the results looked right. How is that different from what J. J. and co. do? Also just like the right wing trolls they were proven wrong later since the actual results did match the poll. They're methodology is irrelevant, that's not what's being attacked.
