The increasingly acrimonious Republican Party primary for U.S. Senate has spilled over to the airwaves this week with Kevin Nicholson and Leah Vukmir trading verbal jabs on talk radio.

One day after Nicholson appeared to dismiss the endorsements Vukmir has received from top Republicans like House Speaker Paul Ryan and U.S. Rep. Jim Sensenbrenner, Vukmir went on air Wednesday to defend the party's senior leaders.

"What the grassroots in Wisconsin can't understand ... why is Kevin not complimentary of our conservative accomplishments, what we've achieved here in Wisconsin," Vukmir said.

Vukmir and Nicholson are vying for the nomination in the Aug. 4 primary, with the winner to face Democratic U.S. Sen. Tammy Baldwin.

The interviews were conducted by Dan O'Donnell of WISN-AM (1130).

Vukmir is the endorsed GOP candidate, winning the backing of 73% of the delegates at the state party convention.
