That was an extremely weak response by Rush to that caller’s question. It was very obvious he didn’t want to deal with the point the caller was getting at in a straightforward manner, so he tap-danced around it until he could figure out a way to steer the discussion back to his desired focus of how it could be used to benefit the Republican Party.
There is no way that Rush, as well informed as he is, can be unaware of which candidates are strong on this issue and which are weak. And, I can understand why Rush would not wish at this time to appear to endorse a particular candidate by by giving a direct answer. However, he should have just said so. Instead he just made himself appear dissembling and evasive.
It seems that Rush is Republican first, and conservative second.
