(CNN) Just months after Republican Kevin Nicholson announced his bid to unseat incumbent Democratic Sen. Tammy Baldwin in 2018, his own parents donated the legal maximum to her primary campaign.

Nicholson announced last July that he would seek the Republican nomination for US Senate in Wisconsin. A Federal Election Commission filing by Baldwin's campaign dated February 5 and available online shows that each of Nicholson's parents, Donna and Michael, donated $2,700 to Baldwin in December 2017. FEC rules stipulate that those donations are the maximumNicholson's parents can donate to Baldwin during the primary election. They can donate up to that amount again during the general election.

Their donations are not necessarily out of character: Nicholson has said on the campaign trail that he comes from a Democratic family and, as the Milwaukee Journal-Sentinel reported in November, his mother has donated thousands of dollars over the years to Democratic organizations and candidates, including hundreds to Baldwin.

However, the contributions are the first his parents have given to Baldwin since Nicholson announced his candidacy to try to oust the senator.

his kid must have really pissed his folks off. This is heartless! A vote is a vote, and I totally get not giving that up because your kid is running: but donating to the opponent’s campaign? That’s brutal! This is like your parents rooting against you in a high school basketball game, except for they’re not only cheering against you: they’re also leading all of the crowd chants and fucking your girlfriend in the stands, and she’s loving it! It’s also not like they’re only donating $20:  they’re donating the absolute maximum possible for a primary!

Ahhhh these people hate their kid. Either that or he must have some twisted policies. You must be a reeaaaaally bad politician to make someone do this- you'd almost prefer that it be because they hate you. What do you have to do to draw this wrath from your parents in the first place? Kill the dog? Clog the vacuum cleaner with the dead dog? Break Mom’s china set? I don’t know! All I know is this is a betrayal unlike any other, and dammmmn next Thanksgiving is going to be awkward, “Pass the mashed potatoes, Mom, also remember that time you stabbed me in the back?”
