Washington, Feb. 16 : Former Republican presidential candidate John McCain has once again sought the help of his ex-running mate and former Alaska Governor Sarah Palin to defend his Arizona seat.
According to The Telegraph, McCain is facing the strongest challenge yet to his 24-year tenure in the US Senate.
"I''m looking forward to getting back on the campaign trail with my former running mate, and I know my fellow Arizonans will welcome her as well," said McCain.
"Sarah energised our nation and remains a leading voice in the Republican Party," he added.
McCain is battling against a right-wing challenge in the Republican primary from J D Hayworth, a former Congressman and talk radio host, who officially started his campaign with a rally in Phoenix on Monday.
