Pollsters go back to drawing board

The Hill reports:

Pollsters who missed Donald Trump’s surprise electoral victory are headed back to the drawing board.

Most polls predicted a Hillary Clinton victory on Election Day, with some positively bullish on the likelihood of a Clinton White House.

The final poll from the Reuters State of the Nation project put the odds at 90 percent that Clinton, the Democratic nominee, would win; The Huffington Post’s model predicted a 98.2 percent chance of Clinton winning; and The New York Times’s Upshot put them at 85 percent.

Both thought that Clinton would win the states of Pennsylvania, Michigan and Wisconsin.

Mistakes were made.
