Ontario County District Attorney Michael Tantillo is on his way out of office, and the Republicans have chosen who they want to succeed him. In the GOP primary, James Ritts has beaten GOP rival Kristina Kitty Karle, 55-to-44 percent. The Ontario County Board of Elections website shows all 92 election districts have reported as of 11 o’clock Tuesday night, two hours after polls closed. Tantillo announced earlier this year that he’s retiring at the end of this term. Ritts currently is First Assistant DA for Ontario County.
