Mr Vance is running for the US Senate seat held by Sen Rob Portman, a Republican, in a crowded GOP primary field in which he trails frontrunners including Josh Mandel. The results haven’t always been pretty, as was the case in the Alabama GOP Senate primary where Rep Mo Brooks won and then later lost the endorsement of Mr Trump, as well as the Pennsylvania Senate primary where Sean Parnell was endorsed by Trump for the seat held by retiring Sen Pat Toomey before domestic abuse allegations forced him out of the race. In Ohio, the Vance campaign’s efforts to overcome frontrunners in the GOP primary could serve as a test that may determine what strength Mr Trump’s endorsement still has among the Republican voter base.
