The federal Liberals have dropped nearly a full percentage point in Mainstreet Research’s latest national polling numbers, providing the first indication Justin Trudeau’s blackface and brownface scandal may be hurting the party’s popularity.

These latest survey numbers capture two full days of polling since the emergence of photos and videos of Trudeau wearing blackface and brownface upended the governing Liberal’s election campaign.

However, the Liberals are still leading the pack with 35.9 per cent of support among leaning and decided voters in the Mainstreet poll, compared to 34.2 for the Conservatives, 10.9 for the NDP, 10.4 for the Greens, 4.8 for the Bloc, 3.1 for the People’s Party and 0.7 for the unspecified other party option.

The Liberal lead, though, falls within the survey’s margin of error, which is plus or minus 2.13 percentage points at the 95 per cent confidence level, according to Mainstreet.

These numbers come from a telephone survey of 2,087 Canadian voters conducted between Sept. 18 and 20. As a daily tracking poll, it’s consistently updated to provide a snapshot of voter preferences over the past three days.

The first media reports unearthing photos and videos of Liberal leader Justin Trudeau wearing blackface and brownface were published on the evening of Sept. 18.

Compared to Friday’s results, the Liberals are down 0.9 percentage points, the Tories are relatively flat, the NDP and Greens are both up by 0.6 points each, the Bloc has risen by 0.1 and the People’s Party is down 0.5.
