I’ve been wrong before, and I’ll be wrong again, but I may never have been as wrong as I was when I initially predicted that Mitt Romney’s heinous diatribe against 47 percent of America would have little direct impact on the election. It’s an absolutely crushing blow. Obviously it doesn’t guarantee his defeat — if a secret video surfaces depicting Obama promising to impose Sharia law in his second term, Romney will stand a good chance of coming back — but it destroys his public standing in ways that make a comeback nearly impossible.
