You are asking about style and social graces that, I believe, never existed. Its pretty clear Dickinson doesn't much care for McCain, but all the same, I think 'mean little fucker' is pretty accurate.

I agree that the 'that one' comment was a poorly aimed attempt at sarcastic humor. I found the above link from 'Thy Goddess', and if I remember correctly, she labeled it 'John McCain is a Misogynist Douchebag'
