Prentice took over as premier from interim leader David Hancock in September. Hancock was installed after Alison Redford stepped down over a series of spending scandals, including a $45,000 taxpayer-funded trip Nelson Mandela's South Africa funeral.
The election was announced on April 7, a year ahead of whats legally required, because Prentice said he wanted a mandate to pass his budget.
The PC budget would have increased some taxes and allow a $5-billion deficit in order to maintain spending schools and hospitals in an era of falling fossil fuel revenue. Royalties from oil and gas have long funded much of Albertas budget.
The Wildrose Party released a platform that promised no tax increases, and a return to balanced budgets by 2017, which would be achieved by reducing the number of government managers and other spending cuts.
The NDP, meanwhile, committed to tax hikes on the top 10 per cent of income earners, and corporations, in order to raise more money for health care and education. The party has also said it would re-examine fossil fuel royalties.
The Liberal Party released a platform that includes a reduction of personal income taxes for the first $50,000, and increases thereafter, to fund things like school construction, reduced post-secondary tuition fees and arts subsidies.
