That wing of the party, McCaskill said on “The Mark Reardon Show” in St. Louis, could offer up a primary challenger to take on the two-term senator when she runs for reelection next year.
"I’m for sure going to run," McCaskill said. "And I may have a primary because there is, in our party now, some of the same kind of enthusiasm at the base that the Republican Party had with the Tea Party.”

In her Thursday interview, McCaskill took aim at her own party, saying that the Democrats haven’t listened to the concerns of voters “that fundamentally think Washington, D.C., is not paying any attention to their needs.”
More ideologically stringent party members have pushed Senate Democrats to reject Trump’s Cabinet nominees and Supreme Court pick on the spot, McCaskill said. Among the 13 Cabinet picks that have been confirmed so far, McCaskill has voted in favor of seven and against five. She said she hadn’t yet decided how she will vote on Supreme Court nominee Neil Gorsuch.
"As of today it's about half and half of the ones I've voted no on and the ones I've voted yes on and I'm making an individual decision based on merit on each one," McCaskill said. "That's not good enough for some of these folks who want me to be just against Trump everywhere.”
