EDMONTON - A new Forum Research poll reports nearly four in 10 decided and leaning voters plan cast their ballots for the NDP on election day, while a quarter say they favour the Wildrose Party and 20 per cent say they will cast their ballot for the Progressive Conservatives.

The research firm says the results from its Wednesday and Thursday night polling represent a dramatic shift from its previous wave of surveys on April 10. At that point, the three main parties were essentially in a dead heat. The Wildrose had 30 per cent, New Democrats sat at 28 per cent and the PCs were at 27 per cent.
