Mark Blumenthal: “The misses were typically small — usually within a single percentage point, although sometimes slightly bigger — but they made a consistent impact on the non-white composition of Gallup’s samples. Instead of achieving the target of 12.1 percent black set by the March 2011 CPS, the average across the seven surveys was 11.3 percent black. Instead of hitting the CPS target of 13.7 percent Hispanic, the seven surveys averaged just 12.4 percent Hispanic.”

But he notes the “real story here is less about Gallup than about the new reality
of public opinion polling. Sophisticated random samples, live interviews
and rigorous calling procedures alone can no longer guarantee accurate
results. Today’s rapidly declining response rates require more weighting
than ever before to correct demographic skews, a phenomenon that places
growing stress on previously reliable weighting procedures.”

Campaigns & Elections: “To poll or not to poll in New Hampshire, that is the question for an increasing number of survey research firms this cycle. Given the state’s new push polling law, is it better for business to take work in the battleground state and risk getting hit with a fine, or is it best to boycott the state and pressure lawmakers to reform the statute?”

“It’s a Hamletesque dilemma for the polling industry, which has been rallying in recent weeks to force a change to New Hampshire’s law. In the past year, several firms have been slapped with hefty fines, and with more enforcement action in the works both sides are digging in.”

Nate Silver: “In the early stages of general election campaigns, a president’s approval ratings have often been at least as accurate a guide to his eventual performance as the head-to-head numbers. Thus, for at least the next couple of months, I would pay as much attention to Mr. Obama’s approval ratings as his head-to-head polls against Mr. Romney.”
