Chris Wallace will undoubtedly bring the SCOTUS issue up in the first debate. It will be interesting to see how Biden answers questions on this. One thing about Wallace, he will bring up what Biden has said about SCOTUS vacancies as a senator, then as VP, and most recently as a candidate. A question like, "While a US Senator in 1992, in a Democratic majority Senate you opposed President George HW Bush's SCOTUS nominee citing it was an election year and the next president should select. In 2016, an election year you said a Republican majority Senate should not hold up President Obama appointing a new SCOTUS. Now as a presidential running mate, you stated the appointment should not be made until a new president is elected. Don't you think it's apparent you believe only a president belonging to the Democratic Party should have the right to appoint a new justice during an election year?"
