Canadian voters are more likely to prefer NDP Leader Tom Mulcair and Liberal Leader Justin Trudeau as prime minister over Conservative Leader Stephen Harper, according to nightly polling by Nanos Research for CTV and The Globe and Mail.

Voters were asked: “Of the current federal political party leaders, please rank your top two current local preferences for prime minister?”

The latest numbers showed 29 per cent of voters prefer Mulcair as prime minister, 28 per cent prefer Trudeau and 26 per cent prefer Harper. Six per cent of Canadians preferred Green Party Leader Elizabeth May as leader and 10 per cent were unsure.

Voters were then asked a series of independent questions for each party leader: 63 per cent responded that Mulcair had the qualities of a good political leader, 54 per cent said the same for Trudeau, while 48 per cent said Harper had the qualities of a good leader -- a new 12-month low for Harper on this measure.

Asked whether May had the qualities of a good political leader, 34 per cent said she did, while 40 per cent (Quebec only) said Bloc Quebecois Leader Gilles Duceppe had the qualities of a good leader.

On the Nanos Party Power Index, the NDP scored 56 out of a possible 100 points on the Index while the Liberals scored 54.3 points, the Conservatives 46.7 points, the Green Party 30.7 points and the BQ 28.4 points (Quebec only).

The Nanos Party Power Index is based on a composite of the following measures: the national ballot, which party voters would consider voting for, the top two choices for prime minister, and whether each party leader has good leadership qualities.

Poll Methodology:

A national dual-frame (land and cell) random telephone survey is conducted nightly by Nanos Research throughout the campaign using live agents. Each evening, a new group of 400 eligible voters are interviewed. The daily tracking figures are based on a three-day rolling sample comprising 1,200 interviews. To update the tracking, a new day of interviewing is added and the oldest day dropped. The margin of error for a survey of 1,200 respondents is ±2.8 percentage points, 19 times out of 20.
