It really has-been an educational week for many people interesting in polling.

Initially arrived the illuminating disclosure that liberal polling organization Public Policy Polling often doesn’t launch the outcome of polls with unexpected outcomes.

After that arrived this interesting article by TNR’s Nate Cohn, showing that PPP’s polling methodology includes a number of dubious practices these types of as “random deletion” of participants.

Then emerged Nate Silver’s statement which he will stay counting on PPP data even though he thinks PPP’s polls are crap.

Drew Linzer, a Ph.D. political scientist who knows their material, likened arbitrary removal to “intuitive ‘shrinkage’ weighting.”

We’re no specialists, nonetheless it seems like he’s saying this can be a technique always get the sample to mirror the population most importantly.

If it feels like smoke and mirrors, don’t worry, because all pollsters take action:

Special envoy for North Korean real human rights problems, Bob King, was expected in Pyongyang right now to seek the release of Kenneth Bae, a Christian missionary who has been held in North Korea since November. Bae was sentenced to fifteen years of hard labor for committing “hostile acts” up against the country and has now experienced poor health. The AP reports that North Korea has withdrawn the invitation and King will go back to Washington.

State dept. spokeswoman Marie Harf stated the U.S. is “surprised and dissatisfied.”

He’s been holed up for days now; maybe alleged cop-killer Christopher Dorner doesn’t know the president’s big state of the union speech is scheduled later tonight. Word is that at least two police officers have been shot and wounded in a standoff with Dorner. While the thoughts of most were with the victims, Howard Kurtz was wondering how the shootout might reflect on the president.

This is on your mind right now?RT @howardkurtz What if alleged killer Chris Dorner is captured or killed as the SOTU begins?

@howardkurtz Really Howard? All you can think about is how your boy king will be hurt if the police take down a stone cold killer? Pathetic.

Hey everyone, calm down. He was just making light of the situation.

Folks, I was making a light point about the SOTU. Obviously concerned about the Dorner shootout and the risk to police brave officers
