Democrat Rodney Glassman spent nearly $460,000 during a two-month period ending on Sept. 30 in his bid to unseat U.S. Sen. John McCain.

Three top staffers have left Rodney Glassman’s U.S. Senate campaign during the past month and a half, and sources close to the campaign said they were driven away by broken financial promises and discontent with Glassman’s management style.

Hoping to breathe life into his struggling campaign challenging Arizona Sen. John McCain, former Rep. J.D. Hayworth on Monday pledged to serve just two terms while fighting illegal immigration and government regulations.

A new survey indicates fewer Arizonans appear to be giving favorable job ratings to the state's two U.S. senators, Republicans John McCain and Jon Kyl.

U.S. Sen. John McCain is spending money like his political life depends on it, pouring more than $15 million into his primary challenge against J.D. Hayworth.
