John McCain is the least popular senator in the country, according to a new poll.
Just 36 percent of Arizona voters approve of the longtime Republican, while 56 percent disapprove, a Public Policy Polling survey found.
Those are the worst numbers the North Carolina-based organization has found in polling more than 90 sitting senators across all 50 states.
"His problem is that voters in his own party don't even like him that much," said Tom Jensen, Public Policy Polling Director.
"When you antagonize your own party base and don't gain popularity with anybody else in the process you're not going to be doing very well."
Just 50 percent of Arizona Republicans approve of McCain, while 39 percent disapprove.
Those number are much worse among Democrats and independents.
