"By Sunday evening, Karzai had received 4,240,041 votes, more than half of the estimated 8,129,935 valid votes cast in the Oct. 9 ballot, the joint U.N.-Afghan electoral board said. That means that even if all the remaining estimated votes went to other candidates, Karzai would still have more than the 50 percent necessary to avoid a runoff.

With 7,666,529 valid votes - or 94.3 percent of the total - counted, Karzai had received 55.3 percent, 39 percentage points ahead of Qanooni."

So no runoff, but it was fairly close. Karzai started with much higher percent and it was lowering as all the votes were counted.

Btw does anyone have information on how the Iraq election will be run and who is running?
