" For Trudeau, a sour ending to a year of progress"
Will the 'progress' has anything to do with the initial borrowing of 10 billion dollars, topping up to 30 billion. 
Yes plenty of infrastructure work, happy OPP, teachers, Unions, special interest groups.
Plenty of  happy liberal voters  find the young, inexperienced PM, attractive, high ratings, as long as the borrowed money keeps pouring in.
