Will a soft NDP vote benefit the Liberals in the next federal election?  Pollster Nik Nanos and host Michael Stittle discuss what the NDP is doing to differentiate itself from the Liberals, after two years of propping them up in Parliament. Also, why Liberal support might actually be higher than the national numbers indicate, and what the 'true' Conservative advantage is over the Liberals.   And as Canadians pay their respects to late prime minister Brian Mulroney, Nik and Michael rewind to 1988 when the Progressive Conservative leader was seeking reelection. His party was trailing the Liberals in the polls but managed to turn it around.  CREDITS: Host: Michael Stittle Guest: Nik Nanos Producers:  Phil Hahn and Patrick Rail Editor:  Jesse Tahirali
