The Senate campaign of Rep. Jerry Moran (R-Kan.) raised $540,000 in the second quarter, it announced Wednesday. That tops primary rival Rep. Todd Tiahrt, who raised $450,987 during the quarter. 

In the run-up to the Aug. 3 primary, the key number is Moran’s cash-on-hand advantage. Moran ended the quarter with some $2.3 million cash on hand to Tiahrt’s $1.2 million. 

Moran’s campaign is also touting new internal numbers that show him leading Tiahrt by 32 points. The internals have been a point of contention between the two camps throughout the race.

Last month, Tiahrt touted his own internal poll that showed the race within a few points. 

The two are vying for the Republican nomination for Sen. Sam Brownback’s (R) seat. Brownback is running for governor.
