We're having this same debate in two separate threads, but oh well.

Of the first 3 results on a cursory internet search, one describes RINO as a Republican who is not conservative enough.

The second explains that it means a Republican who is "too liberal" (As opposed to "a liberal").

The third, however, explicitly defines RINO as "a liberal" who runs as a Republican.

I think clearly the term is ambiguous.

It just goes to show how irrelevant
and powerless Rush and Coulter are
in influencing the Republican
candidate selection.

Coulter hates McCain so much
she'll campaign for Hillary
if he becomes the nominee?

Didn't see that one coming.

Perhaps she can have
more influence again
if she joins the Hillary
camp.
