Internet polls seem to have performed better than telephone polls.
British news networks have called the United Kingdom referendum on membership in the European Union for “leave” in a narrow victory that took most of the night to shake out. The BBC estimates that “leave” will win by a margin of roughly 52 percent to 48 percent.
Polls had indicated the vote would be very close, but most last-minute surveys showed “remain” leading. Two internet pollsters conducted day-of surveys on Thursday that were released after the polls closed. YouGov and Ipsos-MORI both indicated that “remain” would win the day — YouGov had the status quo up by 4 points, and Ipsos-MORI had it up by 6 points.
