Manitoba premier spent less money than rival on leadership campaign

WINNIPEG - Manitoba Premier Greg Selinger raised and spent less money than his main challenger in the leadership race he was forced into and won by 33 votes.

Documents filed with Elections Manitoba show Selinger raised $46,526 for his leadership campaign, and spent slightly less than $48,000.

That's far less than Theresa Oswald, who raised $69,700 and ended the campaign with a small surplus.

Third-place finisher Steve Ashton raised $44,300 — about $16,000 less than he spent.

The new documents show Selinger's donors included union leaders and cabinet ministers who stayed loyal to him — including Greg Dewar in finance and Kerri Irvin-Ross in family services

The leadership race was prompted by a caucus revolt last fall, when Oswald and four other senior cabinet ministers called on Selinger to consider resigning
