This is more than, and more narrow than, a presidential-era bio of John Adams. Rather, it's a precedential bio, to pun on the subtitle, of the second president's presidency.
Several new to me things, without going into spoiler alert details.
First was that Washington, speaking of dealing with precedents and Washington's shadow looming, never invited Adams to a cabinet meeting. They had some minor falling out over Adams' trying to decide on a sufficiently exalted presidential title for GW and he never totally moved off that.
So, with that as a precedent, Adams of course did not invite his pre-12th Amendment Veep Jefferson to cabinet meetings.
Second, there were a few new details to me of Hamilton's machinations via the "Essex Junto" of what the author calls "arch Federalists" about ranks of what were to be Washington's top three assisstants in the Provisional Army.
More new to me is how Adams realized this fairly early on, more than I realized.
Related was the machinations after Adams decided to send a new diplomatic mission to France, post XYZ Affair and how the junto, especially Secretary of State Pickering, tried to gum up the works, but Adams realized eventually what they were doing.
At the same time, by spending a large chunk of 1799 in Massachusetts, he didn't catch on as early as he could have how deep and party-divisive the machinations were.
Meanwhile, the Alien and Sedition Acts are grinding on. Federalists had good results in the 1798 midterm elections and so figured they didn't have to worry about fallout, even though Hamilton of all people said they should do congressional public hearings and make at least cosmetic changes.
Then GW dies and Adams becomes more assertive yet, even as the junto becomes more resistant to the idea of his being the Federalist candidate in 1800. Hamilton engages in more machinations, namely to try to get Federalist electors to substitute Charles Cotesworth Pinckney in the pre-12th Amendment era of the electoral college.
Details of this are new to me.
Finally, the deadlocked election, with plenty before Aaron Burr's smiling duplicity. (Sadly, news that the envoys of Adams' new mission to France had negotiated the Treaty of Mortefontaine, known in the US as the Convention of 1800, did not arrive until after the voting, in a great what-if of history. Maybe Adams would have won, the Essex Junto been crushed, and Jefferson's calumnies related to the actual election been wrong-footed. Surely Adams, though perhaps more cautiously than Jefferson, would have pursued the acquisition of at least New Orleans.)
Federalists, preferring Jefferson to Burr, indirectly/informally approached him early on and he wouldn't even given an informal deal. Eventually, after the multiple ballots in the House, the informal deal that could have been done a month earlier gets done.
Before that point, some of the junto-type Federalists had hoped to stall past March 4 and then controlling the current Congress until November, due to its part-time nature then, name an interim president. Republicans Govs Thomas McKean and James Monroe have Pennsylvania and New York militias ready to march against this.
Jefferson supports the possible recourse to violence and both then and decades later, claimed Adams was linked to this. I won't give away the details.
Especially since he was not invited to any inaugural festivities, is it any wonder Adams left in the morning of March 4?
Chervinsky also handles well how Adams became more confident with Washington's death removing that shadow, and how, long before the 1867 Tenure of Office Act and the 1789 legislation establishing the first cabinet departments, Adams insisted he had the power to fire cabinet secretaries if they wouldn't resign, and eventually did so with Secretary of State Pickering.
Anyway, without too much spoiler, there's plenty here for any serious student of founding fathers American history. Your estimation of Adams will go up to way up; that of Hamilton, and of Jefferson and his two successors, Madison and Monroe, who repeated his calumnies about Adams being a conniving arch Federalist, midnight judges, etc. will go down.
