Probably none, I don't think 2025 is likely to be an election where the Liberals gain seats, especially not ones that are currently safe NDP. But of these four, Vancouver Kingsway. That riding doesn't really have the fundamentals of an NDP+25 seat, so I assume Don Davies is a major factor.
Do you realize that Vancouver-Kingsway is one of the most consistently NDP voting areas in Canada dating back to 1935?! I think Davies has some profile, but its not all about him - the NDP just has extremely strong "brand loyalty" in eastern City of Vancouver and you that also from the way the BC NDP totally dominated the two provincial seats that make up federal vancouver Kingsway. If davies were to retire there would be no shortage of high profile NDPers vying for the nomination
