Brutal Dem primary could pit ex-lawmaker against gov’s sister

Mondaire Jones is gearing up for a potential run for his old House seat, which could tee up a ugly primary with the sister of Michigan Gov. Gretchen Whitmer in must-win territory for Democrats.

While the ex-congressman is publicly saying he’s undecided, four people familiar with his plans say he’s prepping a run for his former New York seat. That’ll likely pit him against Liz Whitmer Gereghty, who has filed federal campaign paperwork and is slated to officially launch her bid soon.

Democrats are bracing for the showdown — in one of several New York districts they need to claw back their House majority — to get nasty.
