I agree with you. However, I’m not sure the attacks are confined to his position on the war, but then I don’t watch the silly “debates”, either. Another poster above describes the same treatment of Rudy. I didn’t select Paul as someone for whom I am a proponent, just someone who might be an example, from the quotes I’ve read, of the object of an exception to the Commandment.
I will agree that people, even here at FR, tend to go for the personal attack instead of rebuting a candidates position. FWIW, I find that sort of thing less here than in most places. In any case, such attacks are always unpersuasive, and can be handily ignored.
