Who are these *progressives* in you opinion?
How have you defined them?
What percentage of the electorate do they make up?
Most importantly, how did they vote in January?
In order, though it is a tad off topic, but for the interest of speaking from the same page on what means what I will answer:
Progressives = Environmental concerns are a priority, equality rights are not up for debate and are a priority to acheive, woman's right to self determination is not up for debate on any level, good governance that is responsible to the people it represents, misogyny, racism and bigotry are societal ills that need to be addressed, anti-war, and I suppose in this day and age electoral reform when combined with the above.
At least 50%
Bloque, Liberal, NDP and Green.
