Kevin Nicholson, a Republican candidate for U.S. Senate in Wisconsin, is using his parents’ donation to Democratic Senator Tammy Baldwin in a fundraising email to potential donors.

You may have heard about my story. I’m running for the U.S. Senate in Wisconsin as a conservative Republican, and I gained a lot of attention recently when a news story broke about my parents:

They made a big donation to extreme liberal Tammy Baldwin, my Democrat opponent.

Here’s the rest of the story. As I shared on “Fox & Friends,” I grew up as a Democrat, and I was a Democrat as a young adult. But, as I saw the destruction and the division the Democrats were causing in our country, I left the Democrat Party and became a conservative Republican.  And I became even more conservative after fighting in Iraq and Afghanistan as a Marine.

Nicholson is running against state Sen. Leah Vukmir (R-Brookfield) in the Republican primary in August, with the winner taking on Baldwin in the general election in November. Madison businessman Eric Hovde, who ran second in the 2012 Republican primary for U.S. Senate, is also considering entering the race.

In the interview on Fox & Friends, Nicholson said that his parents had cut off contact with his family because of politics.

“You know, it’s unfortunate we’re not in contact with my parents,” Nicholson said. “That’s a decision they made on the basis of their politics.”

The fundraising email asks for donations from $3 to $100. When asked if the fundraising email may make Nicholson’s issues with his parents less sympathetic to voters, Nicholson’s spokesman Brandon Moody replied in an email, “Nope.”

In December, Nicholson’s parents and his brother Scott Nicholson maxed out their contributions to Baldwin. Nicholson does not mention his brother in the fundraising email.
