Cavenaugh will never turn into a traitor like Souter, but this is one of the worst possible choices on the list of 25, only slightly better than Hardiman. If you haven't researched him, he has made some of the worst judgements of a non-Obama judge in recent years, including but not limited to being the first judge who claimed obamacare was a "tax" which Roberts used twice to uphold it.
As a judge you don't write the law, you don't "interpret the intention" of the law, you read the plain text and asume what it says it what it means. you don't make it up as you go along. He has to rule according to the constitution, not according to the law he is being asked to "interpret".
Ben Shapiro laid out the case of decision after decision that was wrong and anti-constitutional that Cavenaugh has made in a podecast today, you should check it out.
