Justin Trudeau has raised almost $600,000 during the first three months of his Liberal leadership campaign.

That includes $125,000 donated by some 1,400 individuals in just the last three days of 2012.

Campaign director Katie Telford boasts in an email to Trudeau team members that one fundraiser turned in more than $20,000 on Boxing Day alone.

While a candidate's ability to raise money is no guarantee of success, it is a reliable measure of a contender's ability to build the kind of broadly based grassroots support needed to win a one-member-one-vote contest.

During last year's NDP leadership contest, Tom Mulcair raked in the most money — slightly more than $443,000 over five months — and went on to win the race.

Telford says Trudeau, the prohibitive favourite in the Liberal contest, has already pulled in more money than Mulcair; campaign insiders put the total at close to $600,000 so far, with three months to go.
