The 34-year-old conservative is at the root of discord behind the scenes at ABC’s long-running daytime talk show, earning her the nickname ‘Manic McCain!’ by producers for her inappropriate outbursts on screen and off.

McCain’s spats with co-host Joy Behar, including calling her a b***h on live TV and accusing Sunny Hostin of leaking negative stories about her, have reached such a boiling point that group Hot Topics meetings have been cancelled, sources said.

‘It’s never been this bad,’ an ABC insider told DailyMail.com ‘I’ve been around a long time, but the morale at the show is worse than ever – even worse than when Rosie O’Donnell was here!’…

McCain’s divisiveness has not led to friendship with Behar, Hostin or Friday co-host Ana Navarro, with a source adding they ‘strongly dislike her and Whoopi tolerates her – so they are just co-workers, not her friends.’
