Democratic gubernatorial challenger Gary King's campaign manager has resigned after holding the job about two months.
Keith Breitbach was King's third campaign manager.
King announced the resignation on Monday and in a statement thanked Breitbach for the "positive impact" he had on the campaign.
Breitbach said in an interview he "no hard feelings with Gary or anyone on the campaign."
He acknowledged that King's campaign faced difficulty because it's struggled to raise money and has been outspent 4-to-1 by Martinez since July.
According to the latest poll by the Albuquerque Journal, Martinez has widened her lead over King in the past month.
Breitbach said his elderly mother in Iowa had heart problems and "it is probably best to refocus my attention on my own life."
