IMO, zero is doomed. Zero has no substance, you can’t polish a turd and Romney knows how to get his point across. Romney is becoming a ‘polite’ Newt.
Give it enough time and the right conditions and you can.

In Alaska, they actually polish moose turds for tourist souvenirs. Earrings. Swizzle sticks. A lot of weird stuff.
