A survey released Thursday by the left-leaning Public Policy Polling found that Cruz leads with 38 percent support, with Trump right behind at 37 percent — within the margin of error.

John Kasich follows with 17 percent.

In a head-to-head matchup with Trump, Cruz leads by a wider margin, 49 to 41 percent. The poll found that 51 percent of Kasich voters would support Cruz if the Ohio governor left the race, while 19 percent would move to Trump.

Trump is the only one of the three with a negative favorability. The businessman was seen favorably by 45 percent of voters, and unfavorable by 48 percent.

Kasich was 52 percent favorable and 30 percent unfavorable. Cruz was 50 percent favorably and 36 percent unfavorable.

Cruz and Trump are in a tight race in the Badger State, although polls disagree on how close it is. A Marquette Law School survey released on Wednesday showed the Texas senator leading Trump by 10 points.

The poll was conducted from March 28 to 29 and surveyed 768 likely GOP primary voters. The margin of error was 3.5 percentage points.
