In his bid for the Conservative Party leadership, Andrew Scheer has the bulk of endorsements from current and former politicians.

But because of the rules of the campaign, the contest will be decided in favour of the candidate who can garner the broadest base of support nationwide. Seen through that lens, Scheer's endorsement advantage over Erin O'Toole, Maxime Bernier and Lisa Raitt narrows.

Scheer has 58 endorsements from current and former politicians at either the federal or provincial level. O'Toole has 23, followed by Bernier with 16 and Raitt with 13 (a full list can be found at the bottom of this article).

Michael Chong has received the support of nine former and current elected officials and senators, while Kellie Leitch has five, Deepak Obhrai has three and Andrew Saxton has two. Steven Blaney and Rick Peterson have each received one endorsement.

Chris Alexander, Pierre Lemieux and Brad Trost have yet to announce any endorsements in this campaign.

Among fellow caucus members, Scheer has 24 MPs backing him. O'Toole has 14, Bernier has six, Leitch and Raitt have three apiece and Chong has two.

On Thursday, O'Toole also announced the endorsement of Daniel Lindsay, a Manitoba physician who withdrew from the race last month.

Follow the money

While endorsements are one metric that can be tracked to determine the contours of a leadership race, fundraising is often a more revealing set of data. But the next set of fundraising numbers, covering the fourth quarter of last year, won't be released by Elections Canada until Feb. 1.

Some of the campaigns, however, have already publicized their fundraising totals for the end of 2016. Maxime Bernier announced on Facebook that he raised $583,000 in the fourth quarter, boosting his total to over $1 million for the entire campaign, while Andrew Scheer says he raised $323,570.50 in the quarter.

Erin O'Toole's campaign told CBC News it raised $300,000 to Jan. 11, while Rick Peterson said his campaign raised $71,040 by the end of December, noting he only began to fundraise at the beginning of the month.

Fundraising can signal organizational strength. But endorsements can hint at the same thing, indicating that people within the party recognize a candidate's capacity to win. And in a race where every riding has equal weight, a call from the local MP favouring one contestant over another can be significant.

Scheer's edge narrows with regional weighting

The Conservative leadership campaign will be decided at the local level, as each of Canada's 338 electoral districts will be weighted equally when the votes are counted, regardless of how many members a riding has. That means having a concentration of support in one part of the country might lead to a lot of wasted votes.

Scheer has received 44 per cent of all the endorsements in the campaign — well ahead of O'Toole at 18 per cent, Bernier at 12 per cent, Raitt at 10 per cent and Chong at seven per cent.

But a lot of Scheer's support is concentrated in two provinces. Fully 66 per cent of his endorsements are from Alberta and Saskatchewan politicians, including 20 Saskatchewan MLAs. The two provinces will only represent 14 per cent of all points awarded to determine the winner.

If endorsements are adjusted by the weight each province will have in the leadership vote, Scheer's advantage drops. But it still holds, thanks in large part to the endorsements of four Quebec Conservative MPs that Scheer announced Thursday in the run-up to Tuesday's leadership debate in Quebec City.

Before those endorsements, Scheer's weighted share would have been just 22 per cent. With those endorsements, Scheer's weighted share of endorsements stands at 34 per cent. O'Toole and Bernier follow with 17 per cent each, Raitt with 12 per cent and Chong with seven per cent.

Cluttered field in Ontario

The race for endorsements is closest in Ontario, the province that will carry the most weight in the leadership vote.

O'Toole leads the pack with nine, followed by Chong at seven, Raitt at six, Bernier and Scheer with five apiece, Leitch with four and Obhrai with three.

There's greater separation in the West, where Scheer leads with 43 endorsements (26 in Saskatchewan, 12 in Alberta, three in B.C. and two in Manitoba). Next is O'Toole with 12, Bernier with seven and Raitt with two.

In Quebec, Scheer has four endorsements while Bernier has two.

And in Atlantic Canada, Scheer narrowly edges out Raitt five to four, with O'Toole sitting at two endorsements.

But Scheer's edge in endorsements does not necessarily make him the favourite — it is one metric among others. Bernier was able to raise about as much money as Scheer and O'Toole combined in the last quarter of 2016, while having just a fifth of the endorsements of his two rivals. This suggests he might be having more success resonating with rank-and-file members.

In the end, endorsements are just one factor in a multi-faceted race with a long list of candidates and a preferential ballot that makes being a voter's second choice almost as important as being their first.

At this stage, it seems the Conservative Party establishment thinks Scheer is the one to beat. It won't be clear until May 27, when the results are announced, whether the voting members agree.
