An internal poll conducted for former World Wrestling Entertainment CEO Linda McMahon (R) showed her trailing Connecticut Attorney General Richard Blumenthal (D) by 13 points in the Senate race.

McMahon’s poll, which was conducted June 1-3 by Moore Information, showed her taking 38 percent of the general election vote to Blumenthal’s 51 percent. The survey of 600 registered Connecticut voters had a margin of error of 4 points.

Those numbers are similar to a survey conducted by Blumenthal’s camp in late May. That poll showed the Democrat up by 15 points in a general election matchup.

Both internal campaign polls show a much closer race than the public polling has found.

A Rasmussen Reports survey that was taken about the same time as Blumenthal’s poll showed the attorney general leading by 23 points. A Quinnipiac University poll conducted in late May showed Blumenthal ahead by 25 points.
