Donald Trump's bombastic talk finds an eager audience in Youngstown, Ohio

Donald Trump's simple promises are playing well in Youngstown, Ohio.

His pledge to "make America great again" may not have much substance behind it, but it's what many people in this once booming rust belt community have been waiting to hear.

Youngstown has struggled since its steel mills closed down. Cheap, foreign imported metal did for them and the jobs they provided.

Now, they lie derelict and forlorn. In their shadows, the sprawling housing estates, once home to a vast workforce, are eerily quiet.

Many people here feel forgotten and neglected by the Washington establishment. There's a real anger at a political elite which has done little to ease the community's pain.

So it's easy to see why Trump's bombastic talk of building big and helping the little guy finds an eager audience here.

This place used to be a Democrat heartland - not any more. They ran out of ballots for the Republican nomination here, such was the volume of new party members eager to have a say.

Ken Calhoun was among them. A Democrat all his life, he became disillusioned with politics altogether until Trump came along. His new, explosive brand of politics brought an energy that Ken bought into.

"He cares about the American people", Ken told me. "He'll fight for us and he'll get this country out of the mess it's in. He's proved in his business life that he has the skills to do it," he added, describing Trump as "the blue collar billionaire".

Just as evident as the support for Trump is the distaste for his presidential rival, Hillary Clinton. Many here see her as the very embodiment of the political elite which turned its back on this place.

Connie Spagnola, receptionist at the Republican party headquarters in Youngstown, made her feelings graphically clear when I asked her about Hillary: "I'm sick in my mouth when I think about her," she told me.

In truth, many (perhaps most) voters here have no real love for either candidate, and that could play a big part in the outcome of this race.

In a swing state like Ohio, turnout can make all the difference, so the people who simply don't bother to vote next Tuesday could have just as much of an impact as those who do.
