One should always remember the following when looking at Trudeau's poll numbers: 

1)  Even if supporters of the NDP, Green and Bloc tell a pollster that they are generally "satisfied" with Trudeau, they will still vote NDP, Green and Bloc in the next election. 

2) Trudeau just said good bye to his BC support with approval of the Kinder Morgan pipeline. 

3) The Wynne government is not only setting fire to the Liberal brand in Ontario, but stomping on the ashes and flushing them down the toilet.
