All she's doing is raking in millions of dollars of campaign donations and speaking fees while she is relevant to a portion of the nation. When she's done, she will have a nice comfortable nest egg. The same for Christie and Pence. It's all about getting what they can, while they can.
Lots of minor candidates only run to raise their profiles. The resulting publicity can lead to book deals, talk radio jobs, and TV hosting gigs.
