Sen. Claire McCaskill (D., Mo.) said Wednesday morning she is going to upset a lot of people with her Supreme Court vote whether she votes to confirm Judge Brett Kavanaugh or not, saying the choice is “not a political winner.”

The Missouri Democrat said calls and emails coming into her office are evenly split between those who want her to vote for and against Kavanaugh, Roll Call reports.

“There is no political calculation on this vote. No matter how I vote, there’s going to be a lot of people who are not going to be happy with it,” McCaskill said.

McCaskill said she has to make the case to voters that she is willing to be an independent voice from her party, something she said the Republican nominee, state Attorney General Josh Hawley, will not be.
