"Former US Sen. Rob Portman Endorses Matt Dolan, Shakes Up Ohio Senate Primary"

Ohio Governor Mike DeWine endorsed state Sen. Matt Dolan over Trump-backed businessman Bernie Moreno in the state's GOP primary for a U.S. Senate seat, breaking ranks with Donald Trump and highlighting divisions within the Republican party. DeWine's endorsement is seen as an effort to boost the party's chances of defeating Democratic incumbent Sherrod Brown in November, as Dolan positions himself as a moderate Republican. The move underscores the ongoing struggle between establishment Republicans and the party's pro-Trump faction in Ohio, with the primary election approaching and a large portion of Republican voters still undecided.
