I highly doubt this is why she is staying in the race against Trump.
She’s setting herself up to go third party. If she can siphon off votes from Trump, plus Biden and Harris, she could set up a RFK Jr /Haley ticket.
Ari Fleisscher raised that possibility this evening. She’s running on Democrat money anyway. And this way the Dems don’t have to dump Biden-Harris. She’d play ball with the Deep State.
