Temporary bounce after the comment, lead will come back.
The most damaging aspects of the comment was the ridiculous "mohawk cacaca" justification and the non-apology apology. This underscores what a lot of other people have been saying about Allen's 'unusual' character. Right now, only Katherine Harris out does him on the wacko scale. It won't go away because Allen still hasn't accepted that it exists as a problem. There is no mention of it on his official web site, nothing in the press releases, nothing turns up in the site search bar. Compare this with over 700,000 page hits in Google, or the over 1,000,000 hits on his Confedrate flag fetish.
