Through western Pennsylvania there's not a Hillary Clinton slogan in sight.

The country roads and byways are lined with Trump-Pence signs, banners and flags, and in Youngstown there's a whole house painted red, white and blue. A giant Donald Trump stands out the front.

The house belongs to local property developer Leslie Baum Rossi, who had it jazzed up to motivate Mr Trump's supporters.

It's worked.

"He was saying what people are thinking but don't want to say out loud," one woman says.

She's with her young daughters and they leave with a pile of hats, t-shirts and stickers proclaiming that Mr Trump will "Make America Great Again".

Polls have Mrs Clinton as many as 12 points ahead of Mr Trump nationally, but the numbers are varied.

A CNN/ORC poll today had the margin at five points. In Pennsylvania Mrs Clinton's lead is about six, which mirrors the national average.

That's a reflection of two Pennsylvanias — the urban population around Philadelphia that supports Mrs Clinton, and the rural people affected by mining job losses and globalisation that back Mr Trump.

There's also increasing evidence that level of education drives people to one candidate or the other.

But Mr Trump's supporters believe none of the polls anyway.

"I can't believe them from what I'm seeing," Ms Rossi says.

"I mean, this is such a small town and I have so many people coming here in a week."

She says on the weekends more than 1,000 people each day are visiting the house.

"People come here in large groups. I've had 30 people come and take pictures in front of this statue and they're so excited," she says.

Mrs Clinton has a 20-point lead over her opponent among female voters. The US ABC news poll showed that 69 per cent of likely voters disapproved of Mr Trump's response to questions about his treatment of women, after the release of a lewd tape followed by a procession of women alleging sexual assault.

But for Ms Rossi, it's not an issue.

"It doesn't affect me financially, it doesn't affect my job, it doesn't affect my national security, so I don't really care," she says.

Mr Trump is also dismissing the polls, calling them phony.

Local committee member for the Clinton campaign Phyllis Friend speaks to me among a group of women at the campaign office in Greensburg.

She says she thinks that her candidate will win, but she's not relaxed.

"I am cautiously optimistic that she is going to win but I don't think any of us are taking it for granted," she says.
