One of the ridings Stephen Harper's Conservatives need to hold on to if they wish to win another majority is Huron-Bruce.

It's one of the largest ridings in Ontario and has been Tory blue for 50 of the last 60 years.

It's been Ben Lobb's job to represent the riding in Ottawa in recent years. The young Conservative has won the past two elections.

The last one in 2011 by over 15,000 votes.

"Since 2008, there's been unprecedented investment for a rural community like Huron-Bruce. There's been over $130 million invested here locally. One hundred million [dollars] in infrastructure, roads, sewers, bridges and another $30 [million] in other investments," says Lobb.

But the Liberals are going hard at Huron-Bruce this time.

Former Toronto Star reporter and Glammis native Allan Thompson has been campaigning for the Liberals for over a year.

He wants to return the riding to the Liberal fold, like when Paul Steckle won five consecutive elections in the 90s.

"This is a riding that was Liberal all through the Chretien years. It actually remained in Liberal hands during Harper's first government. So there's a strong Liberal base of support here," says Thompson.

But pundits are having trouble picking anyone but the Conservatives in ridings like Huron-Bruce.

"Conservatives are fairly strong in most of the rural ridings across the country," says Dr. Cameron D. Anderson, associate professor and graduate chair department of political science at Western University.

But that's not stopping Gerard Creces, NDP candidate.

"A lot of people don't realize the NDP finished a very strong second in Huron-Bruce in 2011. We got 25 per cent of the vote. The liberals got 16 per cent of the vote. People are realizing this isn't a two-party system anymore."

Jutta Splettstoesser is counting on the same kind of thinking as she pedals her way around the riding as the Green Party's candidate.

"I'm here because I want to work for you and people are surprised. So you don't have a policy of whipping votes. I say no, we're free to vote for the riding. That's what the Green Party stands for," says Splettstoesser.

Last election, nearly 70 per cent of eligible voters in Huron-Bruce cast a ballot.

That was among the highest percentages in all of Canada.
