A new Abacus Data poll shows the Liberal Party scraping such new lows of unpopularity that they could conceivably be thrown to an unprecedented fourth place in a future House of Commons.

The survey shows just 22 per cent of voters still in the Liberal camp – the lowest ever charted by Abacus since the 2015 election of Prime Minister Justin Trudeau.

But what makes the numbers particularly disastrous for the Liberals is that this new low has coincided with a massive surge in support for the Bloc Québécois.
