PHOENIX -- Ten days after the polls closed in Arizona, Proposition 203, a measure that would legalize medical marijuana is one step closer to winning approval as of Friday afternoon.
As conditional and provisional ballots have been counted throughout the week, the numbers in this closely watched race shifted on Friday. As of 6:00 p.m. on Friday, votes in favor of the measure were 835,735 (50.13%) and votes against Prop 203 were 831,314 (49.87%), which puts the measure ahead by 4,421 votes.
Speaking to the Associated Press earlier in the day, Proposition 203 backer Andrew Myers said he expected the measure to pull ahead when more votes were posted Friday evening.
More than 1.63 million votes have been counted in the 10 days since Election Day. The measure started out losing by about 7,200 votes on Nov. 2 and the gap gradually narrowed in the following 10 days.
The measure was behind by about 1,500 votes as of Friday morning. The vast majority of about 57,000 outstanding votes are in Maricopa County, and most are provisional ballots. County Recorder Helen Purcell said those ballots were leaning toward supporters.
