Speaking at a modest get-out-the-vote rally at the spring training ballpark of the Chicago Cubs, Sen. John McCain (R-Ariz.) revisited an idea he’d walked back last month — that a Republican majority in the Senate would be ready to fight any Hillary Clinton nominee to the Supreme Court.

“There could be as many as three Supreme Court justices that will be chosen in the next four years,” McCain said. “We have to have a Senate who will prevent that four-to-four split from tilting to the left and making decisions that will harm this nation for decades to come.”

That was all McCain said about the court, at a rally headlined by Mitt Romney and covered by MSNBC, CNN and Showtime. But it resembled a remark McCain gave to a Philadelphia radio station last month, promising that Republicans would “be united against any Supreme Court nominee that Hillary Clinton, if she were president, would put up.”

Thursday’s remarks were less explicit, but given that the ninth, empty seat on the court belonged to Antonin Scalia, any Democratic nominee would tilt it to the left. They also came a few hours after Dan Holler, a vice president at Heritage Action, briefed reporters on a no-go strategy toward a possible Clinton court pick.

“You’ve seen John McCain and others talk about the need to not confirm any liberal nominated to the Supreme Court,” Holler said, according to The Hill. “That’s exactly the right position to have.”

Later at the Mesa event, McCain argued that President Obama was wrapping up the “most disastrous presidency in the history of this country.”
