And then there were two.

After months of shaking hands, debating, and passing out flyers, state Rep. Marty Walsh and Boston City Councilor John Connolly emerged from the preliminary election as the final contenders to become the next mayor.

In November, Boston will elect one of these men as the new mayor.

To discuss the race, WBUR's Anthony Brooks and Sacha Pfeiffer hosted a live broadcast of Radio Boston on Boylston Street outside the Boston Public Library.
