Afghan presidential challenger Abdullah Abdullah has called his country's top election official to resign before the Nov. 7 runoff election.

But today, Reuters reports, that official rejected such talk.

"No, why should I resign?" Azizullah Ludin (sometimes spelled Lodin) told Reuters. "I don't know if the constitution gives (Abdullah) authority to ask of such a thing."

Afghanistan's Aug. 20 presidential election was marred by massive fraud. So many of the voters for President Hamid Karzai were eventually tossed out that his share of the total slipped below 50% — forcing the runoff.
