President Obama campaigned for Hillary Clinton in Ohio Friday where the race is tight in this battleground state.

White women could be key in Ohio this year. They make up roughly 40 percent of all voters in the state. And in 2012 — as a bloc — they supported Republican Mitt Romney. But this year, many feel conflicted about the GOP nominee. We revisit women who were undecided when we last met them earlier in the campaign to see how they're leaning as Election Day nears.

This week we're exploring the question: What does it mean to be an American? The country is at a demographic inflection point this election year. The country is changing — it's getting browner.

Asian-Americans are a tiny but growing share of the electorate. In the 1990s, Asian-Americans mostly voted Republican. But in the years since, they seem to have tilted toward the Democratic Party.

Hillary Clinton campaigned Monday in Ohio, where she is facing unfavorable demographic trends as she tries to claim a state that President Obama won twice. But her major focus was a response to Donald Trump's tax story.

Hillary Clinton is campaigning in Ohio on Monday for the first time in weeks. She plans to discuss her vision for a more equitable economy as well as Donald Trump's taxes. Ohio is a state whose demographics favor Donald Trump with a greater number of blue collar white voters. Hillary Clinton has not been in Ohio in weeks but recently received the endorsement of hometown NBA hero LeBron James.

Hillary Clinton spent the day in Charlotte, N.C., attending a church service and meeting with African-American community leaders to discuss the recent shooting of Keith Lamont Scott by police.

Barack Obama won Iowa twice — in part because he did well with white working-class voters. Now, as education and race have erupted as fault lines, can a Democrat still win that demographic in Iowa?

Hillary Clinton is counting on major support from millennials in November. But so far, that generation hasn't been as enthusiastic about her as they were for Barack Obama. NPR explores whether Monday night's debate had any effect on millennials.

Hillary Clinton is struggling to attract young voters. She has not been able, so far, to appeal to as many of them as did the last Democrat who ran for president, Barack Obama. This is a problem for her as she seeks to duplicate the Obama coalition of voters that relied on young voters for his historic victory.

U.S. millennials have overtaken baby boomers as the largest generation. Their economic interests are unique but also diverse — ranging from college debt to affordable childcare and decent paying jobs.

The Hillary Clinton campaign has hired a National Muslim Outreach Director. When Barack Obama's campaign tried something similar eight years ago, it flopped.

Hillary Clinton's campaign is making a national effort to court Muslims this election season. The efforts are mainly concentrated towards Muslim voters in swing states.

Hillary Clinton's remark that "half of Trump's supporters" are a "basket of deplorables" touched off a firestorm in political press, but it seems to barely register for some voters.

Hillary Clinton held a press conference Thursday where she repeated an assertion that terrorists are "praying" for Donald Trump to be elected.

Florida is one of the most hotly contested battleground states this year, and one of the most diverse. Demographic changes there reveal much of why it is such a big prize in the presidential race.

Black voters are key to Hillary Clinton's hopes to win North Carolina. Though every poll shows Clinton with a huge advantage among black voters, there are concerns over turnout.

Historically, white college-educated voters support Republicans, but they seem to be leaving Donald Trump. The demographic is pushing Colorado from a battleground state more toward the Democrats side.

Hillary Clinton is banking on the support of millennials this November. But during the primary season young voters overwhelmingly supported her opponent. So, what's her strategy to win them over?
