Sorry, I agree with Mike...I listened as well.
Mike is correct, Rush did ultimately change his policy on liberal/socialist callers. It's on his web site w/transcript.
However, Rush did not say that he was changing the policy during the caller from Peru, Illinois segment: only that he was considering changing the policy. That transcript is also on the Rush 24/7 web site. That's what I was basing my comment on and did not know that he later made a complete policy change. Mike had the full story, whereas I was ignorant of the later change.
