Conservative commentator Ramesh Ponnuru is dancing pretty close to the edge of GOP apostasy here:

Surely the primary question is whether laws were broken; and if there is serious reason to believe that they were, then shouldn’t there be a presumption in favor of investigation? An argument against prosecution that appears to concede that laws may have been broken, or treats the question as an afterthought, seems to me to be unlikely to prevail. The people who strongly oppose investigation and prosecution would be on stronger ground, it seems to me, making the argument that it is simply outlandish and absurd to think that policymakers violated the law. Can that argument be made?
