IMHO...
The sad part about her being Renfield is that even if she drops out and endorses Mittens, I don’t think her followers are going to go for that. Her’s are definitely more Tea party followers and will go to Perry or Newt or Santorum.
If she drops out and endorses Mitt she’ll be exposed as a fraud who used the tea Party and conservatives to further her own selfish agenda. That would make it very hard for her to keep her seat in Cingress as she may draw a legitimate Tea Party conservative in the primary.
