Unless you agree with Mulcair remarks when Trudeau had Martin & Chretchien by his side. That he was with the "oldies" tour.
It was a poor choice of words, especially given the context of Mulcair's announcement. That said, given that the NDP had been solely attacking the Conservatives and not touching the Liberals (in fact, even openly entertaining the idea of a coalition with the Liberals to get rid of Harper if need be) it was odd how vigorously the Liberals came out to attack the NDP (bringing out Chretien and Martin even to do this). Do the Liberals not see who the real enemy is?
