Don't get ahead of yourself. Her husband would have to win and be seen as a success first, which is possible but not guaranteed.
I don't think either of these things are true. First Lady of Florida to Florida elected office to national presidential contender isn't an insane path even if her husband never becomes president, even if it's not particularly likely. And in the event where DeSantis becomes president and isn't viewed as a success, HW was a one-termer who left office with pretty bad approval ratings, and his party's next president was his son. I don't see any reason to expect either scenario to ever happen, but it really isn't true that her husband's political success is a precondition to her's, if she wants to go into politics and is good at it (two things I have no idea if they're true, I don't know anything about her, I'm being nitpicky for the sake of being nitpicky here)
