Super Tuesday is upon us. In this installment of the 538 Politics podcast, the crew previews what we can expect and debates whether any of it really matters.

Later in the show, Atlanta Journal-Constitution Washington Correspondent Tia Mitchell joins and they turn their focus to Washington, D.C., to discuss Senate Minority Leader Mitch McConnell’s announcement that he will soon step down as head of the Senate Republican Conference and how Congress is responding to the recent ruling by the Alabama Supreme Court regarding in vitro fertilization.
