Two weeks ahead of the federal election, the Conservatives have taken a commanding lead in Alberta among decided voters, a new poll for Postmedia suggests.

The Mainstreet/Postmedia poll shows 63 per cent of decided and leaning voters in Alberta would have cast ballots for the Tories if the election were held on Oct. 1, the day they were polled.

Trailing the Conservatives in Alberta are the Liberals, with the support of 19 per cent of decided and leaning voters, followed by the federal NDP, who received 13 per cent of support among survey respondents.

The poll reveals a three-way race shaping up in Edmonton ahead of the Oct. 19 federal election, with the Conservatives in the lead with 34 per cent support, followed closely by the Liberals at 26 per cent and the NDP at 21 per cent.
