The Alberta Budget of 2013, presented by finance minister Doug Horner, has been the source of endless attacks by the opposition against Premier Alison Redford. Detractors say the provincial budget is a document filled with broken promises and proves Redford and the Alberta Progressive Conservatives misled the province in order to get elected in 2011. But supporters say an unforeseeable drop in the price of the province's oil wealth - referred to as the bitumen bubble - and the premier's determination not to grow Alberta's infrastructure deficit or to gut social programs have the government with little choice but to deliver a budget that will plunge the province deep into the red.
