Although not all of the precincts have been counted, Carmona says that he doesn't believe that the remaining votes will be rnough to give him a win.
As of 11 p.m., Carmona owned about 45 percent of the vote, while Flake was at nearly 51 percent.
Carmona told a teary crowd gathered at a Tucson Marriott conference room that he and his team ran a tough race and that they all could walk away with their heads held high.
He said his supporters fought hard because they "wanted to take our state in a more moderate and sensible direction" and "were tired of seeing Arizona focus on birther bills instead of education."
