Why this race matters
Governor Mike DeWine was term-limited. Vivek Ramaswamy won the May 5 Republican primary overwhelmingly — taking about 82% against sole rival Casey Putsch — with Donald Trump's and the Ohio Republican Party's endorsements. Ramaswamy advances to face Democrat Amy Acton, the former state health director, in November. Vote totals are AP's count via NPR (~99% of precincts).
