So far it is easy to buy votes because of the class warfare on the tax front.  Right now the votes are being bought with someone else's money (ie the 1%ers).  It will be less popular when the money comes, as it inevitably must, from the middle class (ie small business, farmers, doctors, employee discounts, diabetics etc.).

The big one is going to be the Carbon Tax.  It will be a big tax on all Canadians for driving their car and heating their house.  Watch the uproar when voters find out the Carbon Tax is not for big polluters (they will pay only on a portion of their emissions) but for individual consumers (who pay for ALL their emissions).
