First of all what is pork barrel - it is the appropriation of the government for the funding of localized projects.
It was introduce in the early years (1900's) of the republic when the reach of the government is still not in full effect.
Fast forward, Presidents use pork barrel to control / gather support of the congress or just to strengthen his power base. its a numbers game. For the legislators it is were they can pocket money from those funded projects (roads, schools, ports etc.). if your not in the administration block its sure your pork will be delayed.
For me, pork system is already outdated and needs to be abolished. but in order for that to happen the congress must vote for it first
