Gov. Mike DeWine will appoint someone to replace Ohio Sen. JD Vance after he resigns to become vice president.

There was a major shift in the Ohio political landscape on Tuesday night and it has enormous national implications. One of Ohio’s freshman senators has been elected vice president and the other helped Republicans take control of the United States Senate.

J.D. Vance will have to give up his Senate seat when he becomes vice president, but Republicans will still control it and the chamber.

As JD Vance is poised to become the next vice president, his departure from the Senate leaves an opening in Ohio. Here is how the seat will be filled.
