if keystone not approved by obama administration then that is a big plus for gel and paa as well as all other oil transportation companys in the usa.barges ,trains,trucks et.al.will be in great demand to move that black gold.
in addition imho price of oil will keep constant because of this expense.
however in the best interests of the usa and canada this project should be approved.
when cs raised target of gel to 52 it must be in their thinking keystone will not be approved.
all the above just my interpertation.
