Kentucky Attorney General Jack Conway (D) on Wednesday cut his Senate campaign a $300,000 check, according to his latest fundraising report filed Thursday.

Conway, who loaned his campaign over $125,000 last fall, decided to pull out his checkbook again this week, as two new independent polls showed him trailing Lt. Gov. Daniel Mongiardo (D) with two weeks to go before the May 18 primary.

A Lexington Herald-Leader poll on Wednesday showed Conway down 7 points while a Public Policy Polling survey released Tuesday showed Conway trailing by 9 points.

An internal campaign poll released by Mongiardo on Wednesday showed the lieutenant governor up by 12 points. The Conway camp countered with its own poll, which showed the attorney general leading by 6 points.

Conway spokeswoman Allison Haley said Conway decided to loan his campaign the money because he wanted to have the ability to defend himself against Mongiardo’s attacks in the final weeks of the campaign.

Mongiardo has been running his campaign on a smaller budget than Conway. As of March 31, Conway showed more than $2.5 million in receipts over the course of the cycle. Mongiardo had raised just under $1.8 million.

“We have raised more than anyone else in the primary, a testament to our support and momentum,” Haley said. “We are proud to have received contributions this month totaling well over $400,000.”

On the campaign trail, Mongiardo has often described Conway as an out-of-touch elitist born with a silver spoon in his mouth. And his spokesman, Kim Geveden, didn’t miss the opportunity to play up that description again on Thursday.

“Jack Conway and the establishment elites and the political insiders that are backing him are growing more desperate by the day,” Geveden said. “Three polls released yesterday showed Daniel up by an average of 9.3 points. Jack is going to throw more money and more money and more money at this because at the end of the day that’s all Jack has is money.”

Geveden said he wouldn’t be surprised to see Conway open his wallet again before May 18.

The leading Republican candidates are Secretary of State Trey Grayson and anti-tax activist Rand Paul.
