A focus on internet fundraising was a key strategy that propelled Barack Obama into the White House, his chief campaign manager said Monday at a Vancouver event.

Hundreds of internet marketing specialists and business people packed a room at the downtown Vancouver Convention Centre to hear David Plouffe's speech.

Plouffe said Obama's campaign team decided early on to focus on fundraising via the internet and "built the most powerful grassroots fundraising machine" in the world in terms of politics.

"Someone would join our campaign and they would give $25, but they would then start raising money themselves, using our social networking site," Plouffe said.

"And we made sure people understood that we value that as much as the big Beverly Hills fundraisers."

The B.C. election campaign doesn't seem to be having as much success in generating a solid support from online users.

With a day left in the campaign, Liberal Leader Gordon Campbell and NDP Leader Carole James both have fewer than 2,500 supporters listed on their Facebook pages. Green Party Leader Jane Sterk garnered fewer than 300 supporters.
