That's really up to her opponents in the GOP primary. This is how it works. In 2008 she had zero chance to win and probably no one much cared. Did Biden even run an ad against her? Why bother? She was the sacrificial lamb.
It really is up to individual campaigns in primaries and generals to do the opposition research stuff. Castle began doing it when he felt he had to. Anyone with power that supports Castle is doing the same to help him out. This is how primaries work, this is a good thing.
This woman will not win a general election for the Senate seat in November. It just isn't going to happen. If she were a great conservative candidate without all the skeletons flopping out of her closet, I might consider standing with her on principle. Instead, we find she was busy filing gender discrimination suits against conservative groups. This does not sound like a conservative person to me - it sounds like an opportunist.
In a primary you have to consider multiple factors, one of them is - can this candidate win? It isn't just about voting for the most conservative, you have to consider charisma, likability, honestly, polls, etc. Sure, give a ton of weight to the most conservative candidate - but stuff like this lawsuit seriously detract from her value as a candidate.
Pure horse droppings.
