An October poll by Probe research of 1,000 Manitobans shows Premier Sellinger to be by far the most popular party leader with 50% approval while Brian Pallister and Jon Gerrard are at 33% approval. The NDP also leads in voting support with 45%, while the Cons have 38% and the Libs have 11%. The NDP dominates Winnipeg with 52% support while the Cons get only 32% in the city and the Libs trail with 11%. Outside of Winnipeg the Cons lead 46% to 35% over the NDP while Libs receive 10% support there.

It is a long way from an election and polls can change rapidly, but this kind of support would lead to very large majority in MPs elected because of the many seats in Winnipeg.
