Arizona's measure to legalize medical marijuana is still trailing but the gap is closing. The measure was about 3,100 votes below the 50 percent plus one needed for passage after more votes were counted on Thursday afternoon -- by Thursday night when more totals were posted, the measure was losing by less than 1,500 votes. Elections officials say about 14,000 early ballots and 45,000 provisional ballots are left to be processed and counted from the Nov. 2 election.
