My guess is that another reason NH is staying in the race is so that “they” can test cheating schemes.
Multiple reasons for her to stay in, IMO.
As I have emphasized, 💰💰💰 is her biggest challenge. Her determination is not the deciding factor. A candidate needs transportation, TV/radio ads, paid staff, non-voluntary workers, coordinators for precinct action plus poll observers, {secure} communications, expenses ... on and on. I see one of her major donors has just withdrawn financially. That can become contagious among major contributors.
There can be no doubt that the heart of her candidacy is to offer an alternative to DJ Trump, whether it is to replace him if he cannot finish the course or as a third party to split his potential voter support. Any way we cast it, she is in it for Nikki, not for the party, not for America.
One thing she has succeeded in very well is confusing all the pundits❗🤷♂️😄💨
