Ohio Gov. John Kasich leads President Trump in a hypothetical New Hampshire Republican presidential primary matchup, according to a new poll.

An American Research Group poll found that if the New Hampshire Republican presidential primary were held today, Kasich would get 52 percent support, compared to Trump, who would receive just 40 percent.

Another 8 percent were undecided.

In a potential primary matchup between Kasich and Vice President Pence, the Ohio governor still holds an advantage, according to the poll.

In that matchup, Kasich garners 41 percent support, compared to Pence, who has 27 percent.

Another 32 percent of respondents said they were undecided.

The poll was conducted from Aug. 4 to 6 among 600 likely Republican presidential primary voters. The margin of error is 4 percentage points.

The poll comes after a transcript published last week by The Washington Post showed Trump called New Hampshire a "drug-infested den" during a January phone call with the Mexican president.

His comments sparked controversy, and New Hampshire's elected officials pushed back against the characterization.
