(CNN) - Sen. Hillary Clinton has won the February 5 Democratic presidential caucuses in New Mexico, the state party chairman announced Thursday after a count delayed by a large number of provisional ballots.
Clinton, the senator from New York and former first lady, edged out Sen. Barack Obama of Illinois by about 2,000 votes out of the nearly 150,000 cast, New Mexico Democratic Chairman Brian Colon announced nine days after the contest.
The final tally was given as 73,105, or about 49 percent, for Clinton and 71,396, or 48 percent, for Obama.
"With these two Democratic candidates, we had in New Mexico the largest voter turnout in decades," Colon said.
New Mexico is the last of two dozen states that held primaries or caucuses on "Super Tuesday" to complete its count. Colon said the results were delayed as election officials sorted through 17,000 provisional ballots cast during the contest to determine which ones were valid.
Provisional ballots were cast by people whose names did not appear on lists of eligible voters. More than 200 volunteers slogged through the stack of ballots, about half of which were eventually certified, Colon said.
