A former senior Liberal organizer has come out swinging against Justin Trudeau and his bid to become Liberal leader.

John Mraz, who worked as an organizer and consultant to the Liberal Party of Canada from 2003 to 2011 and also assisted in Bob Rae's failed leadership bid, pulled no punches when sizing up Justin Trudeau as a potential Liberal leader.

Should Justin Trudeau be elected prime minister, Mraz argued that among the education and professional backgrounds of every political figure in the G8, he would be the most under qualified of them all.

Mraz also mused that dissent within Liberal ranks on Justin Trudeau is quiet, as Liberals are wary of publicly infighting after years of party division. Commenting on Brian Mulroney's kind words for Justin Trudeau, Mraz noted that it was wise for the former prime minister to ensure that Conservatives do not become complacent.

Mraz is hoping that more leadership candidates come forward.
