Ed Broadbent did you think of this ?

Power Grab could be the result of Proportional representation 

the power grab of horse trading in politics
Let's say the Liberals are 3 seats short of a Majority government
and the NDP happen to have those 3 seats

so they form a Coalition with the Liberals with the demand that
social entitlement be enshrined in the Charter
etc
increase welfare to $30,000 for a single person and $50,000 for families

and for 3 lousy seats they the NDP get this power grab from the power hungry Liberals
politics is dirty
don't be naïve
