"Meanwhile, Fox hosts and producers tell me Ailes has been a somewhat diminished force at the network. In 2014, he took an extended leave of absence after a health scare. He still has trouble walking and rarely ventures out of his executive suite. A friend who ran into Ailes in Palm Beach over the holidays remarked that he was using a walker. 'He seems detached and removed,' one Fox personality tells me. 'He's not around as much,' says another friend of Ailes. 'He doesn't have as many meetings with talent.'
"What this means politically is that during this year's fractious Republican primary, Fox isn't functioning like the disciplined campaign it’s historically been."
