LOL, you must be kidding? There is a significant difference between the Keynesians and the supply siders and I leave that as an exercise for you to figure out.
You'll have to explain "supply siders". This may go along the lines of a "neo-classicalist" but I am not sure as I often here this in the popular media, but having not encountered it in an economic text, I am not sure what it means exactly. You seem to be describing the typical Keynesian formula for success where govt runs deficit during slow grown / recession, backs off in good times, etc.
