The 2016 Ohio Democratic Party Legacy Dinner was at the Greater Columbus Convention Center.
Clinton and Sanders were guest speakers. Sen. Sherrod Brown and former Ohio Gov. Ted Strickland were also in attendance.
"Maybe the time is right to create an economy that works for all of us, not just wealthy campaign contributors," Sanders said during his remarks. "Maybe, just maybe, it's time to end our disastrous trade policies... And tell corporate American that they better start investing in this country, not just China."
He also spoke about raising the minimum wage, guaranteed health care and overturning Citizens United.
"Together we need to build a future where every American has the chance to give up to his or her God-given potential, no matter where you come from, what you look like or who you love," Clinton said, during her speech. "Now, I have to say the stakes in the this election keep getting higher, while the rhetoric keeps sinking lower."
Clinton said Donald Trump is running a campaign of fear and encouraging chaos to get votes. She also said the Democrats are presenting ideas, while the Republicans are presenting insults.
Ohio's presidential primary is on Tuesday. Republican candidates Donald Trump, Ted Cruz and Ohio Gov. John Kasich have also ramped up campaign efforts in the Buckeye State.
