Actually, how conservatives and Liberals feel about her isn't of much concern to me. I was in direct conflict with Coulter on Roberts, have refused to read her columns on the subject since. When the Libs were praising Roberts in obvious strategy to divide conservative support, I stayed by him.
My main objection is that I feel he compromised in the area of expertise and intellectual acumen. I think she's adequate, I do not think she's near the intellect of a Roberts, Thomas or Scalia.
Ideology, who knows? But there was no denying Roberts skills.
