A former Arizona legislator known nationally for championing recent laws against illegal immigration lost as he attempted a political comeback in Tuesday's primary election.
Former state Senate President Russell Pearce lost to businessman Bob Worsley in their race for the Republican Senate nomination in District 25 in Mesa.
Worsley had a 2,600-vote margin with approximately 19,600 votes counted, including thousands of early ballots and results from 14 of 37 precincts.
A year after winning passage of the law known as SB1070, Pearce lost a 2011 recall election largely focused on the illegal immigration issue.
