The USA DOES NOT have a national carbon tax.  FACT!

There is no guarantee that HC will win the US election.

This tax should not be enacted unless the USA and Mexico also enact one in UNISON with ours.  That means no national carbon tax in the USA or Mexico, no Canadian national carbon tax.  Simple and fair.

Saying 'much of the US DOES have carbon pricing' is just political bafflegab.
