The thing about Pain is, unlike all the others, announced and maybes, she has been so thoroughly vetted, there can't be anything else to throw at her. With the others, GOD only knows what's hiding in their closets.
Unlike you, I am positive that she can run a great campaign. She learned her lessons the last time around and understands just how the vast majority of behind the scenes people work. She's NOT going to get sucked in by any of them, this time.
OTOH, we've already seen how some candidates' managers/handlers have botched the job, whilst others don't have the "right" ( as in knowledgeable ) staff at all.
Still others ( Newtie, for one ) keeps stabbing themselves in the back, whilst placing both feet in their respective mouths and then jumping.
I don't have one clear favorite.
Right now only Michele Bachmann, Rick Perry, and Sarah Palin seem at all acceptable to me.
And two of those are undeclared.
I'm not real happy yet.
