As reported in the Chicago Daily News, sister publication of the Chicago Sun-Times:
The Chicago Daily News covered its first Republican National Convention in 1880. Despite President Hayes not running for reelection and former President Grant seeking a third term, the convention had no favorite candidate.
The front page of the June 8, 1880 edition of the paper likely shocked many when it proclaimed, “Garfield Wins,” and described the day’s voting, starting with the 29th ballot.
“There were innumerable rumors concerning various combinations, but none of them could be traced to a reliable source,” the report said. Grant led nearly every vote, but he couldn’t get the 379 votes to clinch the nomination. On the 30th ballot, Garfield had just two votes.
On the 35th ballot, “a whirlwind of a sensation came on this ballot when Indiana gave Garfield 27 votes of which Grant lost,” the report said.
It was enough to spur other delegates to throw their support to Garfield to defeat Grant. So on the 36th ballot, the dark horse candidate won the nomination.
