This is hard for O’Reilly.. he’s always had a fondness for Obama. That has shown in his comments about him and interviews with him. Even though O’Reilly may have some philosophical differences with Obama, he’s still a fan.
Folks in the news business, especially the pundits and commentators are entertainers above all else. News and politics is just their genre, like stand up comedy, song and dance, card tricks. It's all an act and may not represent anything close to what they believe in private. The numbers of real conservatives on television today can probably counted on one hand, two at most.
