Insignificant and petty. The reporter is a twit. Romney is a wishy-washy bore.
Lacks the stuff to go viral.
It's also 4 years old.
Hillary lying about being under sniper fire went viral, years after the fact when she ran against Obama. It was used against her then.

What we want to go viral can be made to go viral if enough people push hard enough.
