The English-language leaders debate Monday night saw federal party leaders fighting to get their platform tag-lines more airtime, while at the same time deflecting jabs from their opponents and firing off some choice zingers themselves.

Everyone was a target during the two hours, but what now? For a leader and their party to evolve, it can pay off when they reflect on the criticism theyve received and adjust their strategy or messaging accordingly. What can the major party leaders learn from the debate?

We asked former party strategists to weigh in on the Justin Trudeau, Andrew Scheer and Jagmeet Singhs performances, and share their analysis on the fairest critiques against each leader and what they and the parties can do post-debate, and with the two weeks that remain, to win over undecided voters and perhaps sway others to switch camps.
