And in particular, let's take a look at the question which considers leaders in absolute rather than relative terms:
More than seven of ten Canadians (72.0%) believe Trudeau has the qualities of a good political leader while 56.3% say the same of Mulcair, 28.4% of Ambrose and 36.5% of May.So which of these theories fits the data?
(b) Tom Mulcair remains a respected leader whose "preferred" numbers in comparison to Trudeau have dropped primarily due to the latter's honeymoon phase.
As during the election, Mulcair is running into the flip side of the axiom that "it's good enough to be a 3 if everybody else is a 2": it's not good enough to be a 6 if somebody else manages to be seen as a 7.
But that doesn't mean any party can reasonably ignore a relatively strong starting point. And so whatever reasons there are for reviewing Mulcair's leadership, his level of public approval can't plausibly be seen as one of them.
