In their potential showdown for the Hawaii’s open Senate seat, Rep. Mazie Hirono (D) and former Gov. Linda Lingle (R) have in the last two days announced their second-quarter fundraising and released dueling polls.

Lingle raised more than $1.1 million in the second quarter, outpacing Hirono, who brought in $941,000 from April to June and had $2 million in cash on hand as of June 30. Lingle did not release her cash-on-hand total.

Unlike Lingle, Hirono is facing a competitive Aug. 11 primary against former Rep. Ed Case, who has not yet announced his quarterly fundraising. Hirono is backed by the Democratic Senatorial Campaign Committee.

Lingle released an internal poll Wednesday showing the Republican leading Hirono 45 percent to 40 percent, while Case led Lingle by 1 point. The survey was conducted July 8-10.

To push back, an internal Hirono campaign poll was released Thursday that showed the Congresswoman ahead 51 percent to 40 percent. The poll of 800 likely general election voters was conducted June 19-21 by Benenson Strategy Group and had a 3.46-point margin of error.

A portion of the Hirono poll results were released last week showing Hirono leading Case in the primary 53 percent to 38 percent. Lingle’s poll found the two Democrats separated by just 1 point in the primary.
