Election 2016: It's Battleground or Bust in the Rust Belt

With just four days left until Election Day, Hillary Clinton and Donald Trump are trying to gain every vote in the key battleground states that will decide the next president. That includes the "Rust Belt" of America, which is especially critical this year.

Near Columbus, Ohio, and in Pennsylvania, Millennial evangelicals are on a push to educate voters and get them to the polls on Tuesday.

Each vote will be especially crucial in Ohio, with Trump and Clinton running neck and neck. That's why the Faith and Freedom Coalition  is knocking on tens of thousands of doors. A personal touch could be the push some evangelical voters need to get to the ballot box.

"I do want to see other Christians get a vote just because it gives them power," said Keionna Riddlebarger, from Ohio Christian University. 

"More and more people want some sort of personal connection and credible persuasion," said Timothy Head, executive director of the Faith and Freedom Coalition said. 

Socialist hero and former presidential candidate Bernie Sanders also came to Youngstown University to rally the troops. Clinton knows she needs Millennials to show up, but students here don't seem too motivated.

"Trump's voters that are my age are much more enthusiastic than the people who are going to be voting for Hillary," Youngstown State University student Ryan Neese said. 

Meanwhile, another battleground state that's in contention is Pennsylvania. Johnstown in particular is a town that was once booming, but as industry moved out so did the jobs. 

"1940 was roughly our high point. We had about 60,000 people in the city,"  resident Donald Bonk told CBN News. "We had a steel mill when I was in high school. In 1979, we had about 12,000 steel workers. We probably have about 1,500 now in various specialty mills."

Both Clinton and Trump are working overtime to win over blue collar, working class American. 

Meanwhile, some people remain undecided, saying they are still unsure of who they are going to vote for.

"This is probably the toughest election and I've been voting since I was 18," one Pennsylvania resident said.

"I'm registered as a R (sic) but right now I'm still pretty undecided," one resident said. 

Others, however, are overwhelmingly in favor of a specific candidate. 

"Trump knows everything that's going on. He's speaking the truth to us. But Hillary knows the house," said another resident. 

With all of the Trump-Pence signs in the area it looks good visually for the Republican ticket. But with Clinton's top-notch ground-game, looks can be deceiving in blue collar America, where this race could ultimately be decided.
