Former President Bill Clinton campaigned for Hillary Clinton in Rochester Tuesday.

While he addressed a crowd of largely Democratic party supporters at the Local Union Post 435 on Fourth Street, his wife’s campaign was busy planning her own appearance in Rochester this Friday.

Hillary Clinton and Bernie Sanders are competing for votes in the New York State Democratic Primary April 19.

“You need to know something about the New York primary,” Clinton told the crowd. “How it comes out, and how strongly you support her, particularly up here where she did so much to change the future for so many as the United States Senator, will shape the whole rest of this primary race.”
