The leadership of Justin Trudeau is generating new interest in the Liberal Party on P.E.I., say Charlottetown MP Sean Casey and Malpeque MP Wayne Easter.

The Island is already a Liberal stronghold, with three of four MPs from that party, and Casey said the base grew during the leadership race.

"We had more than 3,000 people sign up in Prince Edward Island," said Casey.

"I think it's very important that now that we have these people who have shown their interest, who have participated in the process, that we engage them in the building of policy."

Both MPs were pleased to hear Trudeau address the issue of past in-fighting within the party, and to say that era has come to an end. Trudeau won more than 80 per cent of the vote, and on the Island his support was more than 90 per cent in some ridings.

"I think it was 92 per cent in my riding and I believe it was 94 per cent in Egmont," said Easter.

"People want to see hope and opportunity and that's basically what Justin's message was."

The Conservatives responded quickly to Trudeau's election, issuing new attack ads against him.
