What a horrible way to have to begin a presidency.
No question about it. Just imagine the gradual awakening that must have occurred between Trump being informed by Mike Rogers that Trump Tower was wiretapped; after which, the next day he picked up all campaign operations and moved them to NJ; then the Comey meeting; then the gradual discovery that surveillance activity was carried out on him via Page & Papa for at least a year and possibly more before the election; and that all these agencies were working against him and are likely working against today as I write this.
The Comey meeting, I will speculate, must have been the crucial turning point where he realized how deeply embedded and determined the entire IC was working against him. Not to mention a solid 1/3d of Congressional Republicans pre-Mueller report.
