Other than exciting the base, I see no real benefit to the Party from her stumping.
She's been hell on obamacare, and very pro-gun. I'd call those beneficial.
Has she changed any minds regarding those issues? I don't believe so. If in fact she has in our favor she has been beneficial.
It appears to me she is always preaching to the choir, and that has little benefit if any.
Again, I agree 100% with her message.
