Republican presidential contender Marco Rubio suggested on Meet the Press on Sunday that he would appoint Supreme Court justices willing to overturn the June 2015 Obergefell ruling on same-sex marriage rights; he's previously been critical of the ruling but doesn't seem to have previously brought up the idea of actively reversing it. From the show's transcript:
RUBIO: ... What is wrong is that the Supreme Court has found this hidden constitutional right that 200 years of jurisprudence had not discovered and basically overturned the will of voters in Florida where over 60 percent passed a constitutional amendment that defined marriage in the state constitution as the union of one man and one woman.
CHUCK TODD: So are you accepting the idea of same sex marriage in perpetuity?
RUBIO: It is the current law. I don't believe any case law is settled law. Any future Supreme Court can change it. And ultimately, I will appoint Supreme Court justices that will interpret the Constitution as originally constructed.
A Pew poll in July found that Americans support same-sex marriage rights by a margin of 54 percent to 39 percent. Only 34 percent of self-identified Republicans in that poll, however, supported marriage equality, with 63 percent opposed.
