A day after Casey's call for Trudeau to step down, what do the other 3 Island MPs say?

A day after Charlottetown Liberal MP Sean Casey publicly called on Prime Minister Justin Trudeau to step down as party leader, CBC News asked the Island's other three Liberal MPs where they stand.

Only Lawrence MacAulay, the veteran MP and cabinet minister from Cardigan, provided a concrete response, saying he continues to support Trudeau's leadership of the Liberal Party of Canada.

"It was under Prime Minister Justin Trudeau's leadership that we lowered the retirement age back to 65 and boosted OAS for seniors 75 and over, made historic investments in our infrastructure and small craft harbours, delivered the Canada Child Benefit and $10-a-day child care, dental care, and pharmacare, and made massive steps forward on the environment," MacAulay said in an email statement.

"These are the things that matter to Islanders, and he has my full support."

Malpeque MP Heath MacDonald declined an interview but staff said his office would issue a statement in support of Casey's position. They later called back to say there would be no statement Wednesday.

There was no response from Egmont MP Bobby Morrissey.

Casey, meanwhile, said his phone has "blown up" with messages of support following his exclusive interview with David Cochrane on CBC's Power & Politics on Tuesday, where he said he agrees with what he is hearing from his constituents that "it is time for [Trudeau] to go."

But there has also been some online "hate," he said in an interview Wednesday afternoon.

"The feedback that I've received from people in the riding and from people that I know has been overwhelmingly positive and supportive. And the feedback that I've received on social media, especially Twitter, is filled with hate."

He said about half a dozen fellow Liberal MPs, including Morrissey and MacDonald, have complimented him for speaking out. 

"The only ones who are reaching out to me, I would say, are those who feel the same way as I do and haven't yet stated so publicly."

In an earlier interview Wednesday on CBC-Radio's Island Morning, Casey said people have told him they don't want another four years of Trudeau, but don't like the idea of Conservative Leader Pierre Poilievre as prime minister either.

"I knocked on 500 doors this summer, I've knocked on about 4,000 in the last year and a half, and you get on somebody's doorstep and they look you in the eye and they say, 'I'm scared to death of Poilievre, Sean. I want to vote for you, but I just can't' — over and over again."

The CBC's Poll Tracker suggests the Liberals are trailing the Conservatives by roughly 20 percentage points.
