COLUMBUS — Embattled Republican Rep. Max Miller is staying in the race for his Ohio congressional district, defying voices within his own party who urged him to step aside as he faced domestic abuse allegations from his ex-wife. President Donald Trump won the GOP-leaning district comfortably two years ago. Miller won it with just 51% of the vote two years ago in a three-way contest that included former congressman and presidential candidate Dennis Kucinich, who ran as an independent. While both of Ohio’s senators, including his former father-in-law, Sen. Bernie Moreno, called on him to drop out of the race, Trump never did. The then-32-year-old jumped in to challenge Ohio Rep. Anthony Gonzalez, a popular former professional football player, who ultimately dropped out.
