“In the flood of election polls you’ll see over the next few weeks, most polling groups will include responses from ‘likely voters.’ And often from nobody else,” the New York Times reports.
“In theory, these poll numbers should yield more accurate results, since the people who actually vote are the ones who dictate the outcome on Election Day. But creating a precise picture of who will vote in November is a complicated endeavor.”
“After all, how exactly can a pollster know who is ‘likely’ to vote, and who therefore will be the focus of their results? There’s no one right answer, and every polling firm has its own strategy.”
