We CAN amend the constitution... We can allow all party members as of the date of appointment of the new leader to vote on a constitutional amendment to allow for a 2yr window to select the next leader. An online vote can be done quite easily. Also a "local" ballot in ridings across the country. The latter option would also allow Liberals to gather one more time post-election... Great way to begin people thinking about party reform.
We CAN do it. We just need to - as needed - break with "tradition". The Constitution can be amended. There is no need to shy away from that. As a matter of fact many of the needs of this party may require constitutional changes.
