Ohio Republican Congressman Max Miller is refusing to drop out despite mounting abuse allegations, a mess that could hand his seat to Democrats.

• Miller gave a long speech denying he abused his ex-wife, releasing doorbell footage and texts he says prove she stayed friendly with him afterward.
• The abuse claims go beyond his ex-wife — a former Trump White House aide and old high school and college accusers have made similar allegations over the years.
• One recording Miller released seems to undercut him: after denying he scalded his ex-wife with hot water, he can be heard admitting the water incident happened.
• His ex-wife's father, Republican Senator Bernie Moreno, publicly called him a danger and said he should quit — the only elected Republican to do so.
• Miller is firing back at Moreno with hints of "dirt," while other Republicans stay silent to protect their thin House majority and follow Trump's lead.

Outlook: Ohio's withdrawal deadline is August 5th and Miller shows no sign of dropping out, leaving a Trump-won district unexpectedly in play for Democrats.
