"He was my favorite senator... I love him. He made the liberals squeal"

This quote by Robert Novak is likely referring to a senator who was a favorite of his, and who was likely a conventional. Novak likely appreciated this legislator for his conventional sights as well as the reality that he was able to make the liberals squeal. This can mean that the senator was able to pass regulation that was not favored by the liberals, or that he was able to make a solid disagreement versus the liberal viewpoint. It could also mean that the senator had the ability to make the liberals awkward with his sights as well as point of views. Whatever the situation, it is clear that Novak admired this legislator and boasted of his ability to defend his beliefs and also make the liberals screech.
