I think this is an open primary and she knows the GOP want to run against her... she just does not want to lose in the primary
And the GOP should vote for her- a new democrat has a possibility of winnng. She will lose in a landslide of epic proportions
She should easily be in the top 2 for the primary, and with the Republicans splitting the vote, will likely be the front runner coming out of the primary. If she can be held below 50%, she’ll lose in the runoff, unless the Tea Party voters boycott the runoff.
