Too many children in this part of Ohio's Appalachian country live in unstable homes with a parent facing addiction. For years, the community has struggled with opioids. Ohio had the second-highest number of drug overdose deaths per capita in 2016, according to the Centers for Disease Control and Prevention.

When North Korea released three U.S. prisoners last Wednesday amid increased engagement with Washington, the families of U.S. citizens detained in Iran couldn't help but wonder about prospects for their own loved ones. Just a day earlier, the U.S. withdrew from the Iran nuclear deal and reimposed economic sanctions on Iran. For the detainees' relatives, it has been a painful and uncertain time.

It was the first day of school for Dan Lear's three kids. In a scramble to get his boys to class on time, the Seattle lawyer wound up parking in a space he probably should have avoided.

"There was a fire hydrant, but the curb wasn't painted and the fire hydrant was painted a kind of a funny color. And so I thought, and maybe it was wishful thinking, but I thought I would be OK to park there," he says.

Sure enough, Lear returned to a ticket.

Ohio has almost always voted for winning presidential candidates. The state has backed the winner in 28 of the last 30 presidential elections.

This year, the race is tight here, with some polls showing Democratic nominee Hillary Clinton modestly ahead and others putting Republican nominee Donald Trump in a slight lead.
