Once again we see just how bad many of these liberal polling groups are with a look at the hash they made with their predictions of the 2018 elections.
One thing most did have right is that the Democrats would take control of the House of Representatives — an easy guess, really — but what most got wrong was by how many that new majority would grow. Most thought there was going to be a massive “blue wave” of new Democrats winning election and streaming into Washington.
In reality? Not so much.
Rowan Scarborough noted all the major misses by pollsters:
Florida governor: The last 10 polls had pegged Democratic Tallahassee Mayor Andrew Gillum the winner. But former Rep. Ron DeSantis won by 0.7 percentage points. While some wrong polls lay within the margin of error, Quinnipiac College in New York picked Mr. Gillum to win by 7 points. The St. Petersburg poll, NBC/Marist, Emerson College and the University of Florida had Mr. Gillum winning by 4 to 6 points.
Florida Senate: Nearly every late survey picked Democratic Sen. Bill Nelson to retain his seat. He lost to GOP Gov. Rick Scott by 0.4 percentage points. Again, Quinnipiac was way off, predicting a 7-point Nelson win. Emerson College also botched it, saying Mr. Nelson would win by 5 points. The St. Petersburg poll nailed the race at a 1 percentage-point Scott victory.
Missouri Senate: Several polls missed Republican Josh Hawley’s 6 percentage-point win against Democratic Sen. Claire McCaskill. NBC/Marist had her up by 3 points. Emerson and the Republican firm Trafalgar correctly saw the Hawley win, at 3 and 4 percentage points, respectively.
Georgia governor: Trafalgar badly overestimated Republican Brian Kemp’s final tally. An outlier in this race, the company said Mr. Kemp would defeat Democrat Stacey Abrams by 12 points. He won by 1.6 percent. Emerson and the Atlanta Constitution were spot on.
Nevada Senate: Trafalgar missed this race, forecasting a 3 percentage-point win for GOP Sen. Dean Heller. Democrat Jacky Rosen won by 5 point
Indiana Senate: Fox News badly missed here, predicting an easy win for Democratic Sen. Joe Donnelly against Republican Mike Braun. Fox said Mr. Donnelly would win by 7 percentage points. He lost by 7.8 points, meaning Fox was off by 14 points. NBC/Marist also saw a Donnelly win, by 3 points.
Arizona Senate: Again NBC/Marist was off, saying Democrat Kirsten Sinema would win by 6 percentage points; CNN said by 4 points. Republican Rep. Martha McSally is leading by 2.2 percentage points, but a large number of mail-in ballots are still to be counted.
Ohio governor: A number of forecasters botched this race. Former Sen. Mike DeWine beat Democrat Richard Cordray by 4.3 percentage points. NBC/Marist’s last poll had it a tie. Quinnipiac had Mr. Cordray up by 2 points, Emerson by 3 and Gravis by 5 in their final polls.
