Ten days after the general election, Arizona's medical marijuana ballot measure appears to be headed toward passage as Maricopa County election officials race to finish counting early and provisional ballots.

Just before 6 p.m. Friday, the Secretary of State's Office reported the measure was leading by more than 4,000 votes. It was the first time the measure had more yes votes than no votes since the ballot tally began Nov. 2.

Arizona’s medical marijuana proposition is still losing by more than 3,300 votes, a gap that has stayed relatively steady over the last 24 hours. But it’s still too close to call Proposition 203, as 78,000 early and provisional ballots remain to be counted.
