The results of the New Hampshire primary might look good for Donald Trump’s prospects to win the Republican nomination. And yet, according to the PollyVote, the Democratic party is the real winner of yesterday’s election. As a result of Trump taking back the lead in the PredictWise GOP nomination forecast, PollyVote’s forecast of the Democratic two-party vote share in the general election has increased by 1.2 percentage points to currently 51.5% (vs. 48.5% for the Republicans). This is the largest lead for the Democrats since PollyVote published its first forecast on January 1st, 2016.
The Pollyvote team has completed its second survey of elections experts to forecast the 2016 presidential election. In the late January survey, conducted between January 26 and 30, 17 academics from a variety of colleges and universities responded. The mean forecast is that the Democrats will garner 52.0% of the major-party vote, compared to 48.0% for the Republicans. In the previous survey, conducted in late December, the experts had predicted a vote share of 51.7% for the Democrats and 48.3% for the Republicans.

The Pollyvote team has completed its first survey of elections experts to forecast the 2016 presidential election. In the late December survey, conducted between December 26 and 31, eight academics from a variety of colleges and universities predicted that the Democrats will eke out a narrow victory over the Republicans. The mean forecast is that the Democrats will garner 51.7% of the major-party vote, compared to 48.3% for the Republicans.
The Pollyvote team will conduct similar surveys monthly until fall 2016, when the experts will be polled more frequently.
This is the fourth presidential election campaign in which an expert panel has been formed by the Pollyvote team to forecast the election outcome. The first surveys, those in 2004, did not begin as early as the current survey, but those for 2008 and 2012 did. In 2012, the late December survey revealed an average forecast of 50.6% for Obama, who eventually received 52% of the two-party vote; a forecast error of merely 1.4 percentage points. In 2008, the late December survey predicted McCain to gain 47.7%. Again, this long-term forecast was off by only 1.4 percentage points, as McCain eventually won 46.3% of the vote. Thus, even with this long lead time, the expert panelists were able to forecast the winner in both elections. As we see, the experts have considerable expertise in forecasting elections. Watch this space for the next report from the experts in about a month.
Correction note: A previous version of this article incorrectly stated that the mean expert forecast was 51.9% for the Democrats and 48.7% for the Republicans.
Today, the PollyVote published its first forecast for the 2016 election. Her first forecast of the national popular two-party vote predicts a virtual tie, with the Democrats at 50.1%, and the Republicans at 49.9% of the vote.
The PollyVote first started in 2004 by political scientists and forecasting experts and has accurately forecast US presidential elections since then. For details about the procedure as well as historical data, see the published research or read the FAQ.
We will have some exciting additions to the PollyVote in 2016. Stay tuned!
