No one is “troubled” by Cain or Bachmann running because it is obvious neither one is going to get the nomination.
It is delusional to believe the Left is worried more about the above than about Perry. It knows very well how easy it would be to marginalize either of the above and how difficult it would be to do the same with Perry.
There is also no doubt the potential nominee the Left fears and hates above all is Sarah. I have never seen anything like the tsunami of hate it unleashed on her and her familty.
Actually, I find it rather amusing what you started out with there. We’ve actually seen it on this forum already.
If nobody is concerned about Bachmann, then why was she targeted here?
