It is certainly a convenient time for an Ailes depature from a Hillary Clinton perspective, given that Donald Trump has been a long-time friend of Ailes and we are headed into the intense final strecth of the election season.
Nothing better for Hilalry than a "fair and left-tilted" FOX News.
Lew Rockwell thinks Hillary might have been behind it:
Is this a Hillary coup? I worked with Ailes on some political commercials at the beginning of the ’80s. An impressive guy, now brought low by organized feminism? I don’t know, but Gretchen’s lawyers are major-league Hillarians.Ailes will leave immediately.
