The Ohio Republican Party will hold an election for state chairman on Friday that GOP insiders are monitoring for clues as to how far President-elect Trump’s takeover of their party will go.

In that contest, forces aligned with Trump are trying to purge sitting Ohio GOP Chairman Matt Borges as punishment for his loyalty to Gov. John Kasich, who declined to endorse the president-elect over Democrat Hillary Clinton. Kasich and a slew of state and local officials are backing Borges.
