Trump's approval rating just dropped to a new low in his favorite poll

President Donald Trump's approval rating just dipped to a new low in the latest Rasmussen poll, the survey that is often most favorable to Trump.

Rasmussen found Monday that just 39% of likely US voters approve of the job Trump is doing, while 61% disapprove of the president.

It was the first time Trump dipped below 40% in the Rasmussen presidential tracking poll.

As recently as mid-June, Rasmussen had Trump's approval rating at 50% - far beyond where other polls found Trump's approval rating to be.

At the time, Trump tweeted, "The new Rasmussen Poll, one of the most accurate in the 2016 Election, just out with a Trump 50% Approval Rating.That's higher than O's #'s!"

Rasmussen interviewed 1,500 likely voters over a three-day period, with a margin of error of 2.5 percentage points.
