In a nation more associated with calamity than consensus, the initial results of Saturday's Afghan presidential election are startling.

Despite Taliban threats to attack polling stations nationwide, the same percentage of Afghans turned out to vote — roughly 58 percent — as did Americans in the 2012 U.S. presidential race. Instead of collapsing, Afghan security forces effectively secured the vote.

And a leading candidate to replace Hamid Karzai is Ashraf Ghani, a former World Bank technocrat who has a Ph.D. in cultural anthropology from Columbia University, a Lebanese Christian wife, and an acclaimed book and TED talk entitled "Fixing Failed States."
