They haven't won a seat in the city since 1968, but longtime political watchers say the Liberals have a shot at capturing a seat in Calgary in this election.

How much money local candidates are raising could be one indicator, according to The Strategists on CBC Calgary's newscast.

Veteran Alberta campaign strategist Corey Hogan says Calgary Confederation candidate Matt Grant is one of the top fundraisers in the country.

"He's running quite the campaign and I think if he wins it will be entirely because of organization," says the director of engagement at Hill+Knowlton Strategies.

Grant is facing off against former PC MLA Len Webber, who left the party under premier Alison Redford, NDP candidate Kirk Heuser and Natalie Odd from the Green Party.

Hogan adds the Liberals' recent increase in national polls makes the party more viable here in the heartland of the Conservative Party.

He says voters like to back winners.

Up to 3 seats?

Another longtime political strategist is also betting on the Liberals winning a seat in Calgary in this federal election.

Stephen Carter, who was former premier Alison Redford's chief of staff, thinks at least two other Liberals — both former MLAs — have good chances in this campaign besides Grant in Calgary-Confederation.

Darshan Kang in Calgary Skyview is taking on Conservative Devinder Shory, Sahajvir Singh for the NDP and Edward Reddy of the Green Party.

"The three candidates who really are in a race, they are raising money, they've got volunteer teams and they look like they might be able to win it," he said.

Carter adds Liberal candidates could also benefit from Liberal leader Justin Trudeau's recent more muted rhetoric about Alberta's energy industry.

Trudeau has also visited Calgary a couple of times in recent months.

The party has had few MPs elected in Alberta, where the memory of Pierre Trudeau's National Energy Program (NEP) still stings.

The last Alberta Liberal MP, Anne McLellan, lost her seat in 2006.
