Meghan McCain was on Wednesday’s Watch What Happens Live With Andy Cohen, and the daughter of former Republican presidential nominee John McCain may have GOP in her DNA, but for the upcoming presidential election, she probably won’t be voting for her party.

When asked about the 2020 election between presumptive Democratic nominee Joe Biden and President Donald Trump, McCain refused to say who will be getting her vote. However, she did say, “I keep telling everyone I will promise you will know who I'm voting for but it won't take a rocket scientist to know.”

Joe Biden was a long-time friend to the McCain family and even spoke at John McCain’s funeral. Whereas Donald Trump did not attend the funeral and has repeatedly attacked the war hero and long-time Arizona senator.

“There is one who has made pain in my life a living hell and another man who has literally shepherded me through the grief process,” said McCain, reiterating, “This really shouldn't be rocket science.”

The View co-host called out the entire Trump family, saying, “The Trumps, they're always making my mom cry.” And even though McCain didn’t officially say she was voting for Joe Biden, it’s pretty obvious she’ll be checking that box this November.

Watch What Happens Live With Andy Cohen airs Sunday to Thursday at 11 p.m. on Bravo.
