"I promise you that we will be united against any Supreme Court nominee that Hillary Clinton, if she were president, would put up. I promise you. This is where we need the majority and Pat Toomey is probably as articulate and effective on the floor of the Senate as anyone I have encountered."Here's the later clarification from a McCain spokesperson:
"Senator McCain believes you can only judge people by their record and Hillary Clinton has a clear record of supporting liberal judicial nominees.... That being said, Senator McCain will, of course, thoroughly examine the record of any Supreme Court nominee put before the Senate and vote for or against that individual based on their qualifications as he has done throughout his career."So I guess the point is that a GOP Senate will demand a nonliberal nominee. If Hillary Clinton responds properly to that pressure and nominates someone with a record that demonstrates nonliberalism, the GOP Senators will vote for that person.
