I only listed elections where a flip of 15,000 or less votes would have changed the outcome. I think I listed all of those elections below.
2000: 269 votes (1 state: FL)
1876: 445 votes (1 state: SC)
1884: 575 votes (1 state: NY)
1916: 1,887 votes (1 state: CA)
1844: 2,554 votes (1 state: NY)
1888: 7,187 votes (1 state: NY)
1976: 9,246 votes (2 states: OH+HI)*
1880: 10,517 votes (1 state: NY)
1960: 11,874 votes (5 states: MO+IL+NV+NM+HI)
*Assuming that the one Reagan elector would have voted for Ford as pledged
1800 (NY) and 1812 (PA) were incredibly close but I cant figure out the number needed to flip them.
