The conservatives will include just a sprinkling of poison pills - nothing egregious, nothing that would resonate strongly with the general public - but enough that the opposition parties will have a very hard time supporting it.
Now since prorogation effectively killed all legislation that was on the table, the Home Renovation Tax Credit is also dead. So the conservative narrative will be "well we wanted to offer this great tax credit to Canadians, but the opposition parties have decided to take that away by voting against the budget. Don't blame us. Blame the Liberals."
In other words, I fully expect to be blackmailed with my own money in March.
