Political science professor forecasts Trump as general election winner

A professor of political science at Stony Brook University has forecasted that Donald Trump has a minimum 97 percent chance of winning the general election as the Republican nominee.

Professor Helmut Norpoth’s forecast presentation took place Monday evening in the SUNY Global Center in Manhattan, which was organized by the Stony Brook Alumni Association.

Norpoth created a statistical model of presidential elections that uses a candidate’s performance in their party’s primary and patterns in the electoral cycle as predictors of the presidential vote in the general election.

Donald Trump has a 97 percent chance of defeating Hillary Clinton and a 99 percent chance of defeating Bernie Sanders in the general election, according to Norpoth’s formula.

“The bottom line is that the primary model, using also the cyclical movement, makes it almost certain that Donald Trump will be the next president,” Norpoth said, “if he’s a nominee of the [Republican] party.”

Norpoth’s primary model works for every presidential election since 1912, with the notable exception of the 1960 election. These results give the model an accuracy of 96.1 percent.

Norpoth began the presentation with an introduction of the potential matchups in the general election, including a hypothetical Sanders vs. Trump general election.

“When I started out with this kind of display a few months ago, I thought it was sort of a joke.” Norpoth said referring to Trump and Sanders, as many alumni in the audience laughed. “Well, I’ll tell you right now, it ain’t a joke anymore.”
