The federal election race is officially under way, and the Conservatives, Liberals and NDP appear to be in a three-way race as they leave the starting line.

The latest ballot tracking from Nanos Research shows a razor-thin margin of voter preference support separating the first-place Conservatives from the NDP and Liberals, in a survey that asked respondents which two parties they would consider voting for in their local riding.

Stephen Harper’s Conservatives led the survey results with 31.5 per cent support overall, followed closely by Thomas Mulcair’s NDP at 30.1 per cent, with Justin Trudeau’s Liberals trailing at 29.3 per cent support. The Green Party ranked a distant fourth in the survey with 5.4 per cent support.

“The trend has been favouring the New Democrats,” pollster Nik Nanos told CTV News on Sunday.
