The poll with the best track record over the last three presidential elections gave Donald Trump a 2 percentage-point edge over Hillary Clinton on Saturday.

The Investor’s Business Daily/TIPP tracking poll has Trump at 42.1 percent and Clinton at 39.7 percent.

The IBD/TIPP survey, which includes 791 likely voters and carries a margin of error of 3.6 percentage points, was the most accurate predictor of the final results in the last three presidential elections — calling the outcomes within 0.9 percent of the actual tally in 2004, 2008 and 2012.

Trump pounced on the poll results. “Great new poll this morning, thank you. Lets #DrainTheSwamp and #MakeAmer­icaGreatAgain!” he tweeted.

Clinton has a 95 percent chance of winning, according to a Reuters/Ipsos electoral-vote analysis from last week.
