Health Care Polls: Silver on Question-Order Effects

Nate Silver suggests that unusually low levels of support for health care reform in FOX News polls may stem from question-order effects.

R2K Polling Controversy

On June 29, 2010, the website Daily Kos announced that polls it had commissioned from the firm Research 2000 were "likely bunk." Kos has asked readers to disregard all R2K polls done for his site. Any Kos/R2K polls cited here on the Health Care Polls blog over the past several months should accordingly be disregarded, as well. I am leaving them up, however, as part of the historical record. Often, my analyses of polling trends that included R2K surveys also included polls from other firms, too. I hope the pending lawsuits between Kos and R2K will reveal whether the latter's polls are completely valid, completely made-up, or perhaps, as Nate Silver suggested, the product of data being merely "mangled."
