UPDATE: Via the lovely, talented - and alert! - Leslie Carbone, Ms Todd has confessed to it being a hoax.
It's a weird thing to say I hope I'm wrong on this issue - if the attack was real as alleged, then there's an Obama supporter out there who's just nuts (gee, surprise). But if Ms Todd is lying, she needs some serious help, and it's going to be a nasty backlash against McCain.
Basically it's a no-win situation.
A lot of people have been weighing in on this (just take a look at Michelle Malkin's post), and many seem very skeptical.
Personally, I have no issues with the backwards "B," but I do wonder about its superficiality and neatness. Believe me, I've cut myself often enough in the kitchen to know that knife wounds aren't so nice unless very carefully done. If this woman was struggling - or if she was immobile in fear and the attacker was in a hurry - there is NO WAY that B would have been so well-formed, and the cuts would have been far more ragged.
I just don't know.
As for her refusal of medical treatment, well, I've been in a couple of situations myself - as well has hearing a story or two from my Beloved - where stress and the high-emotions of the moment haven't led me to make the most rational of decisions. Therefore, I easily see Ms Todd refusing treatment. Heck, who knows?!, she may have a religious reason for refusing medical aid.
Again, I just don't know.
But I am feeling cautious and a more than a bit skeptical.
