Sherrill won Morris County overall and even won my very wealthy, very Republican precinct (maybe the first time a Democrat has EVER won my precinct, certainly the first in my living memory). She won by even more than Gottheimer AND Van Drew, so most likely she isn't going anywhere barring some unforeseen scandal or if she seeks higher office (which I have to imagine she'll go for at some point). And if she is going to be dislodged it won't be done by the guy who managed to lose one of the most historically Republican districts in the country by 13 points.
Hopefully she runs for the open seat in 2024 (please god let Menendez be gone by then.)
