Rush wants guests that make him look good. The Rush Limbaugh show is about The Rush Limbaugh show.
He has Gingrich on as well, who has screwed us over royally.
Money speaks louder than hype.
I guess you cannot tell the difference.
And besides Rush initiated the Trump appearance last week. I would guess that Newt asks Rush to appear when he does, and out of some historic sense of loyalty he accedes.
