After St. Paul's, is there anything Trudeau can say or do to save his leadership?

I wonder what would happen if he announced tomorrow that he had a really good acid trip the other day and came to the conclusion that what the government must do is abandon the F-35 jet fighter deal, stop subsidizing oil companies, stop subsidizing car companies, stop pretending that rapid population growth is good for us, nationalize most of the telecom sector, get serious about fighting back the power of the other oligopolies that run most of the country, double the carbon tax, cut the income tax, eliminate most of the deductions that make it so complex, tax capital gains at the same rate as other income, consult with economic experts willing to design an effective regime for preventing businesses from growing too large, renew efforts for electoral reform, cancel all the bad Internet bills, fund electrified passenger rail transport, and run all government systems with 100% free software.
