Ramaswamy, 39, is set to kick off his campaign in Cincinnati, joining the 2026 Republican primary just a month after presumed frontrunner and then-Lt. Gov. Jon Husted left the running to take a U.S. Senate appointment.

Ohio Governor Mike DeWine nominated Tressel on Monday to replace Ohio's previous lieutenant governor, Jon Husted, who is now serving in the U.S. Senate.

Jim Tressel will fill the void left by former Ohio Lt. Gov. Jon Husted, who was tapped by Gov. Mike DeWine to replace Vice President JD Vance in the U.S. Senate.

Jim Tressel, 72, succeeds Republican Jon Husted, who was appointed last month to the U.S. Senate seat formerly held by Vice President JD Vance.

The 72-year-old is taking over for Jon Husted, who left the position last month to fill the U.S. Senate seat vacated by JD Vance when he became vice president.

Tressel will take the place of former Lt. Gov. Jon Husted who was named last month to fill the Senate seat that Vice President JD Vance vacated.

Ramaswamy joins a competitive GOP primary field to succeed Republican Gov. Mike DeWine, 78, a veteran center-right politician who is term-limited.
