A Keynesian stimulus hardly works. It's been tried many, many times, with always the same results: close to none, or ending up in worse situation in the mid-term, by modifying the market incentives and removing cash that would be invested somewhere else by private entities. It is not about not liking one's government, this kind of government intervention is opposed to democracy and free market.
Well, spending tons of cash that does not belong to you (but to the taxpayers) to favor certain interests and not others can hardly be called democratic. Only free markets are democratic, hence you will see that stimulus are largely employed in authoritarian regims rather than actual democraties.
