Oh but there is.
"Voting for Burr would humiliate Jefferson. Initially, Hamilton agreed, confiding to Adam's secretary of the treasury, Oliver Wolcott, that it might prove useful to "lure" Burr into a compromising situation that would ultimately prove difficult for him, that is to 'lay the foundation of dissention between two chiefs.'" (source: Isenberg's Fallen Founder, primary source: Hamilton Papers)
And then the pivot
"When Hamilton realized that House Federalists were more than willing to elect Burr, he was startled and dashed off frantic letters to all the key congressional leaders. Horrified that Burr might become the head of his party, he pleaded with Theodore Sedgwickand others: 'For heaven's sake let not the Federalist party be responsible for the elevation of this Man."' (source: Isenberg's Fallen Founder, primary source: Hamilton Papers)
That is no evidence at all. Finding something useful is not equivalent of actually doing it, and encouraging the House Members to vote for 35 ballots for Burr.
It doesn't prove at all that he conspired to put Burr over Jefferson. Even Fallen Founder, a biography of Aaron Burr, did not put forth any evidence that Hamilton actively encouraged House Federalists to put Burr in the White House. Sowing dissension among the two does not equal convincing the House Federalist members to vote for Burr. That was all the initiative of the House Federalist caucus.
Show me one letter from Hamilton urging the congressmen to vote for Burr and Burr would be a better President for the Federalists instead of Jefferson and that he should be become president over Jefferson and I'll be convinced.
On the contrary, he actively discouraged Federalists to vote for Burr and elect Jefferson. He never considered Burr to be better than Jefferson, and there was nothing, nothing, that suggest that Hamilton encouraged other congressmen to vote for Burr over Jefferson.
And he did so for two months, meaning beginning in December 1800, when it was clear that the result was a tie of 73 for Jefferson and Burr each. So from the very beginning, he was urging the House Federalists not to vote for Burr and to elect Jefferson.
The only conspiracy he did was to actively convince the Federalists to back away from the consensus of the Party to back Burr, and to extract from Jefferson an assurance that he will keep his financial system.
So no. There is no evidence at all.
Autocrat said:
The vote was close, but killing off Hamilton doesn't give Adams the state. You are exactly correct to say that the state legislature appointed the electors and yes Manhattan (where Burr carried all 13 seats) was the most important election of New York, because it ensured a majority in for Republicans in the lower house. And that is exactly why your wrong. First off the Federalist platform was unremarkable, just several unknown merchants. They were going against the Republican slate of George Clinton, Horatio Gates, Henry Rutgers, and John Broome (all of them war heroes), influential New York merchants, and the well known Brockholst Livingston. And the campaigns that supported those candidates. One of course is Burr's well run machine. The other was not sabotaged by Hamilton, but run Hamilton, one of the biggest New York political insiders. And during the day of the polls Hamilton personally rode around the city to polling stations to rally the Federalist vote. Without Hamilton, the Federalist platform in new York will be far worse off.
Hamilton did not sabotage the Federalist effort in New York, he ran it.
I'll again quote McCollulough for the whole text.
"Despite the malicious attacks on him, the furor over the Alien and Sedition Acts, unpopular taxes, betrayals by his own cabinet, the disarray of the Federalists, and the final treachery of Hamilton, he had, in fact, come very close to winning the electoral count. With a difference of only 250 votes in New York City, Adams would have won with an electoral count of 71 to 61."

So yeah. Even after all the blunders of the Federalists, of Adams, of Hamilton, of the unremarkable Federalist platform, and the brilliant efforts of Burr, of Gates, of Livingston, of Burr's well run machine, all that they could achieve was a tiny margin of 250 votes. It's even smaller than the 537 votes of Florida in 2000.
Everything is against Adams and for Burr and Jefferson, and yet, only 250 votes in Manhattan signified the difference between victory and defeat.
So yeah, any small number of things could turn the state to Adams.
