Betts: The 1980 United States Senate election in Ohio took place on November 4, 1980. It was concurrent with elections to the United States House of Representatives. Incumbent Democratic U.S. Senator John Glenn won re-election to a second term in a landslide with nearly 69% of the vote, coinciding with Republican President Ronald Reagan's substantial win in the state during the concurrent presidential election. Glenn carried all but one of the state's 88 counties, only losing Paulding County.

Glenn won the senate race by a state-record of 1,633,091 votes. George Voinovich came within about 100,000 votes of this margin in his 1994 race for Governor. He had also won the largest percentage of the popular vote and received the most votes in any U.S. Senate election in the state's history, and as of 2024 (the most recent senate election), Glenn continues to hold the record of having the highest percentage of the popular vote in an Ohio Senate Race. However, George Voinovich won a larger percentage of the popular vote than Glenn did in the 1994 Ohio Governor Race. His percentage margin was 6.25% larger than Glenn's 40.55% margin.

Also in 2004, Voinovich, however, would beat Glenn's record of receiving the highest number of votes in an election, receiving nearly 3.47 million votes (nearly 694,000 more votes than Glenn got)
