Victor Davis Hanson succinctly sums it up.

If all this is not a scandal — then the following protocols are now considered permissible in American electoral practice and constitutional jurisprudence: An incumbent administration can freely use the FBI and the DOJ to favor one side in a presidential election, by buying its opposition research against the other candidate, using its own prestige to authenticate such a third-party oppositional dossier, and then using it to obtain court-ordered wiretaps on American citizens employed by a candidate’s campaign — and do so by deliberately misleading the court about the origins and authors of the dossier that was used to obtain the warrants.
