Presidential contenders Donald Trump and Hillary Clinton are virtually deadlocked in the Rasmussen Reports poll, released Tuesday.

The right-leaning pollsters find Clinton led Trump 42 percent to 41 percent in a poll with a 2.5 percent margin of error. Libertarian and Green Party candidates Gary Johnson and Jill Stein poll at nine percent and two percent, respectively.

And, the pollsters noted, the race is tightening:

Eighty-three percent of voters now say they are certain how they will vote, and Clinton has a statistically insignificant 48 percent to 47 percent lead among this group. Among the voters who still may change their minds, it’s Trump 31 percent, Clinton 27 percent, Johnson 32 percent and Stein 10 percent.

Rasmussen Reports surveyed 1,500 likely voters on September 29 and then from October 2 and 3.
