Not even a Keynesian should think that government stimulus always works (though the "always run a deficit" slogan is dangerously close). Imagine an economy at "full employment" and generally regarded as prosperous. Could the government make things even
better by deficit spending, and send the economy to the moon? The intuition here is that the government would "crowd out" private investment with fiscal policy. And the government's idea of what to invest in should not be on par with what the market will opt for, even for a Keynesian, as a Keynesian does accept a market as the right economic model. To believe fiscal spending would make us even richer at "full employment" would urge us very far left to central planning -- we might as well give the government all our money and let them build everything, if they can make capital allocation decisions this much better than the market can.
Keynesians believe occasions arise where the economy gets stuck below full employment. They believe a "market failure" prevents the normal mechanisms from kicking in for a rebound. At this point, they believe intervention can get the economy past a snag. This does not mean that the investments; bridges, health care, or whatever, need to be spectacularly picked, they just need to be adequate to kick-start the engine.
Those who doubt Keynes argue that crowding out, among other things, will still be relevant in scenarios below "full employment," that if healing through investment is needed, the private sector will already be accommodating and government investment "crowds" this out. But there is a broad spectrum of beliefs among those who doubt Keynes.
What it really boils down to is whether or not "busts" or recessions present us with market failures. If they do, then intervention from government is on the table as a solution. Most conservatives would argue that some scenarios are extreme enough -- the great depression for instance -- where intervention must happen, but in general, fiscal and monetary policy just slush around to no avail, or worse. On the extreme right are folks like me -- far more to the right than Droopy and BCSpace in market belief -- who do not believe downturnes are the result of market failures at all, meaning, there is never a real motivation to intervene. If the economy is 20% of what it was last year, then it's 20% of what it was, perhaps a meteor hit the earth, and fiscal/monetary policy will just shift things around or hinder recovery, no matter how extreme the scenario.
