Some candidates who are running for either the US House of Representatives or the Senate have seen vocal and public opposition from some of their own family members.
In Wisconsin, Democratic candidate Randy Bryce has seen his brother appear in campaign videos for his Republican rival Bryan Steil.
While Mr Bryce has tried to use his blue-collar background as a way to gain support to fill the outgoing Speaker Paul Ryan’s seat, his police brother, James Bryce, has appeared in an ad for Mr Steil.
In the ad, James says: “I don’t think people want to be represented by someone who shows contempt for those in law enforcement.”
The ad then showed photos of arrests involving Randy for marijuana possession and driving drunk.
He has since apologised for the incidents and condemned the use of “divisive, dirty politics that people are fed up with”.
In Arizona, Paul Gosar has seen his siblings call him a “racist” and criticise his policy stances.
His sister Grace said in a video: “It would be difficult to see my brother as anything but a racist.”
Mr Gosar has previously peddled conspiracy theories, such as calling billionaire George Soros a Nazi collaborator as well as calling the white supremacist all in Charlottesville last year the work of “the left”.
In July, Mr Gosar spoke in London in support of Tommy Robinson.
He told CNN that his siblings were “liberal Democrats who hate President Trump” and that “Lenin, Mao and Kim Jung (sic) Un would be proud”.
Missouri Republican candidate Steve West has been called an anti-semite by some of his children and that he has only become more extreme over the years.
Emily West said: “I can’t imagine him being in any level of government.
“He’s made multiple comments that are racist and homophobic and how he doesn’t like the Jews.”
Mr West has continually refuted these claims saying that he is “absolutely not anti-Semitic”.
The midterm elections take place on November 6 will early voting throughout the US breaking multiple records.
There are over two dozen Republican seats in the House that are at risk of being taken by the Democrats.
