I tivo'ed Matthews daily and can attest that he was against invasion, saying again and again, invasion would simply create more enemies and history showed we would be repelled. Yes, he can be a chameleon as he buddies up with guests on all sides, on all issues, and one just tuning in occasionally could mistake his position.)
Ritter was my guiding light and I was fascinated at how consistenly the media distorted his historical and current positions to make him look crazy and that he had done a 180 when in truth he was remarkably consistent. Every single time he was a guest the preface was, "So, you said this but now you say this!"
Pat Buchanan, an interesting voice, was openly against invasion and never budged an inch.
