'I told you so': The one pollster who is sure Donald Trump is going to win

In 2016, its first time publicly releasing polls, Trafalgar was the firm whose state surveys most effectively presaged Mr. Trump's upset win

If President Trump pieces together an Electoral College win on Tuesday, at least one pollster — and perhaps only one — will be able to say, “I told you so.”

That person is Robert Cahaly, whose Trafalgar Group this year has released a consistent stream of battleground-state polls showing the president highly competitive against Joseph R. Biden Jr., and often out ahead, in states where most other pollsters have shown a steady Biden lead.

Trafalgar does not disclose its methods, and is considered far too shadowy by other pollsters to be taken seriously. Mostly, they dismiss it as an outlier.
