Final PollyVote forecast: Clinton will win

All numbers are in and, according to the PollyVote, Hillary Clinton will become the first female president of the United States.

Popular and Electoral Vote Prediction

Clinton will win the popular vote by 5.0 percentage points in the two-party vote (52.5% vs. 47.5%). Based on the PollyVote’s historical error, Clinton’s chance to win the popular vote is above 99%. In terms of the Electoral College, Polly predicts Clinton to receive 323 electoral votes compared to 215 for Trump.

Forecast over the course of the campaign

Forecasting is useful only when it can aid decision-making. Thus, Election Eve forecasts are only for entertainment and betting— and writing victory and concession speeches.

The PollyVote has predicted Clinton to win beginning with its first release in early January 2016. Since the first Super Tuesday on March 1st, when it became clear that Trump would become the Republican nominee, Clinton’s lead in the PollyVote forecast averaged 5.6 points. Throughout the course of the campaign, it ranged from a minimum of 3.8 points to a maximum of 8.2 points. In other words, the PollyVote never had Trump close to winning.

Since its launch in 2004, the PollyVote has always correctly predicted the winner on any given day, months in advance, and with little forecast error. Tonight, we will find out whether Polly the Parrot will keep her clean slate. Check back in the days to come as we will provide analyses of the different forecasting methods’ accuracy.

Democrats gain after NH primary

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.

First PollyVote forecast predicts close race

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.
