Democrat Richard Carmona is tied with likely GOP nominee Jeff Flake in this year's U.S. Senate race, according to a new Public Policy Polling survey.
The PPP survey, commissioned by the League of Conservation Voters, shows that both candidates have the support of 38 percent of voters.
The survey also shows that Mitt Romney is leading Barack Obama, 52 percent to 41 percent, among Arizona voters.
