Both Connecticut Technology Council President and CEO Matthew Nemerson and State Rep. Gary Holder-Winfield both officially dropped out of the mayoral race and endorsed State Sen. Toni Harp ARC ’78 earlier this week. With two candidates leaving the race in just three days, the crowded field of candidates is now down to five contenders.

Harp initially endorsed Holder-Winfield’s campaign before she joined the race herself in late April. Holder-Winfield, who has worked alongside Harp in the General Assembly, told the New Haven Independent that he will probably run for Harp’s seat in the senate if she wins the election unless State Rep. Toni Walker is also interested in the position.

Both Nemerson and his campaign treasurer will now serve Harp’s campaign as co-chairs of its steering committee, according to the New Haven Independent. Nemerson praised Harp’s ability to build broad coalitions and gain support from a wide base of constituents during a Monday speech.

Harp also has endorsements from various aldermen, including Board President Jorge Perez and Ward 1 Alderman Sarah Eidelson ’12, as well as the Central Labor Council, which represents 13 unions.

If Harp wins in November’s election, she will become the Elm City’s first female mayor.
