Where Undecided Voters Stand After First Presidential Debate

— -- According to the Sunday's ABC News/Washington Post poll, 17 percent of registered voters were planning on watching last night's presidential debate with an open mind, saying Hillary Clinton's and Donald Trump's performances might change their minds about how they would vote.

Three young undecided voters in three swing states spoke with ABC News about their impressions the morning after that debate.

Lacey Dickinson, a 28-year-old nonprofit staffer in Philadelphia is torn between casting her ballot for Clinton or Green Party candidate Jill Stein.

Carolyn Garavente, 24, a project manager from Greensboro, North Carolina, has always identified as Republican but says she doesn't believe Trump represents her interests.

And Peter Macone, a 32-year-old restaurant manager from Manchester, New Hampshire, says he hasn't been persuaded to shift his support from Sen. Bernie Sanders to Clinton and is weighing writing in the former Democratic candidate on principle.

With just six weeks to go until Election Day, what will these undecided voters ultimately decide?
