Feud Alert! Bill O'Reilly Doesn't Stephen Colbert Can Compete In The Late Night Arena!

First Rush Limbaugh and now Bill O'Reilly ?

Before getting selected as David Letterman 's Late Show replacement, Stephen Colbert was called an "ideological fanatical" and a "deceiver" by Bill!

Whoa, that's a pretty wild accusation there, Bill!

Now, Bill has since calmed down his rhetoric and called Stephen an "interesting choice," but has doubted whether he can compete with the high energy of Jimmy Fallon and Jimmy Kimmel .

Uh, have you even seen Stephen? He's got stage presence for days, and enough energy in his comedy to power a small robot. He'll be fine, Bill.

On top of all this, Bill questioned whether or not conservatives would watch his Late Show:

"It'd be hard to fathom that 40 percent of Americans that describe themselves as conservative will watch Colbert. And that's a lot of folks to lose."

We think Stephen's stand-up (no pun intended) character and hilarity are enough to keep viewers watching. Our money would bet that he does a great job at 11:30 p.m.!
