3. Well that knocks Newt out as Romney's replacement if it goes that far.
People don't like to see overt crazy. This is why Romney got the nomination. Most the other candidates displayed overt craziness. Except for Huntsman(he is probably loony as well) he was the only other candidate that appeared to be sane. You have to be careful as a Republican, you can't appear too sane, but you can't be Bachmann insane either.
