U.S. Senator Chuck Grassley is sticking to his promise not to play favorites in the GOP primary for the open U.S. Senate seat. Last week news emerged that Grassley will be a “special guest” at fundraisers for his former chief of staff, David Young. This week both Matt Whitaker and Sam Clovis revealed that Iowa’s senior senator has offered to be a guest at fundraisers for their own Senate campaigns. Whitaker said in a statement that he looks forward to Grassley’s “help and his counsel”. Clovis told the Des Moines Register,

“He wanted to commend me for being in the race,” said Clovis, a Sioux City conservative radio personality and college economics professor. “He said he had to remain neutral in this primary … and he wanted to make sure everything was being played even.” […]

Clovis said he and the senator have “a great relationship” after years of animated discussions on the radio.

Grassley has repeatedly expressed concern that Representative Bruce Braley, who is unchallenged in the Democratic primary for Senate, will go into the general election with a financial advantage.

Speaking to Cameron Joseph of The Hill, The Iowa Republican blogger Craig Robinson sounded a more skeptical note: “Yes, Grassley says he’s neutral, but nearly everyone connected to him is supporting Young. Appearance and perception are two different things. The whole Grassley operation is helping Young.”
