The [Democratic] party is stoking skepticism in the final stretch of the midterm campaign, providing a mirror image of conservative complaints in 2012 about “skewed” polls in the presidential race between President Obama and Republican Mitt Romney.
Democrats who do not want their party faithful to lose hope — particularly in a midterm election that will be largely decided on voter turnout — are taking aim at the pollsters, arguing that they are underestimating the party’s chances in November.
At the center of the storm, just as he was in 2012, is Nate Silver of fivethirtyeight.com…
This year, Democrats have been upset with Silver’s predictions that Republicans are likely to retake the Senate. Sen. Heidi Heitkamp (D-N.D.) mocked Silver at a fundraising luncheon in Seattle that was also addressed by Vice President Biden, according to a White House pool report on Thursday.
“Pollsters and polling have sort of elbowed their way to the table in terms of coverage,” Berkovitz said. “Pollsters have become high profile: They are showing up on cable TV all the time.”
This phenomenon, in turn, has led to greatly increased media coverage of the differences between polling analyses. In recent days, a public spat played out between Silver and the Princeton Election Consortium’s Sam Wang, which in turn elicited headlines such as The Daily Beast’s “Why is Nate Silver so afraid of Sam Wang?”
There are lots of good questions to ask about political polls, including looking at their sampling, the questions they ask, and how they make their projections. Yet, that doesn’t automatically mean that everything has been manipulated to lead to a certain outcome.
One way around this? Try to aggregate among various polls and projections. RealClearPolitics has a variety of polls in many races for the 2014 elections. Aggregation also helps get around the issue of celebrity where people like Nate Silver build careers on being right – until they are wrong.
At the most basic level, the argument about flawed polls is probably about turning out the base to vote. If some people won’t vote because they think their vote won’t overturn the majority, then you have to find ways to convince them that their vote still matters.
