I have no objection to agreeing with a RINO when he agrees with my principles. My objection would be to altering my principles to conform to a RINO.
MacArthur’s objection was to signing a document that he agreed with (anti-gay marriage) because people that he disagreed with (Catholics) also signed it. That doesn’t make much sense.

But do you object to people like Snowe, Collins, Specter (before he “came out”) posing as Republicans while voting like Democrats?
That is a misreading of MacArthur. MacArthur explains exactly why he wouldn’t sign it; t isn’t because Roman Catholics signed the documents.
