Cuomo and Duffy are expected to appear together at a press conference today.
Duffy, 55, is just beginning his second term as mayor, where he is pushing for mayoral control of city schools. Duffy is a former police officer and chief of Rochester's police force.
Those who know Duffy also point out that his demeanor is well-suited to the number-two position, where a principle requirement is not to outshine or hold larger ambitions than your boss, the Albany Times Union reported this morning.
New York Democrats, who kicked off their three-day convention yesterday, will formally select a candidate for lieutenant governor this afternoon.
On Tuesday, Cuomo, the current attorney general, said he was looking for someone who would bring “competence, performance and integrity” to the position.
Meantime, Democratic officials announced that all five attorney general candidates will appear on the primary ballot at the same time.
A Siena College poll on Monday found no strong candidate to replace Cuomo as attorney general.
