PHOENIX -- Democrat Harry Mitchell's lead over Republican Rep. J.D. Hayworth increased as elections officials continued to count ballots Monday in the 5th Congressional District race.

Mitchell had a total of 88,302 votes, or 50 percent. Hayworth had 82,485 votes, or 47 percent, according to the Secretary of State's office, which continues to compile early and provisional ballots.

Libertarian Warren Severin had 5,578 votes, or 3.2 percent.

The Associated Press called the race for Mitchell last Tuesday.

Hayworth has not conceded the race. Elections officials say it will take several days to finish counting the more than 100,000 ballots that remain.

Meanwhile, Mitchell continued to organize a congressional transition team as he spent a second day at an orientation session in Washington, D.C., for newly elected Democratic members of Congress.

Arizona's 5th District includes Scottsdale, Tempe and parts of Chandler, Mesa and Phoenix.
