If you like numbers, this is a pretty good description of the outcomes of the BC Conservative leadership vote. (It is still political commentary, of course.)
If youâre going to read one data analysis piece on the BC Conservative leadership race, make it this one. #bcpoli @BIVnews @shxnhugh

Something I don't get about Vancouver's move to densify "villlages" first, rather than "neighbourhood centres" (already existing large commercial strips): Why?

Fun fact: AMOC collapse leads to an ice age within a few years. This isn't theoretical, it's happened prior. Humans are going to learn the hard way, as usual...

Cool to see SFU snag the largest-ever donation in its history: a $40 million gift from Arran and Ratana Stephens and their family.
Chatted with Arran today about his rationale, and how it is a "vast percentage" of his savings.

There were about 1000 more voters Outside Metro Vancouver.
The voter district distribution for this leadership vote likely reflects things like the depth of the party's local organizations, candidate networks, etc.

In terms of Black and Milobar:
Black had primarily a Metro Vancouver/suburban breadth.
Milobar had primarily an Interior regional concentration, particularly around Kamloops, which is not surprising given his origins.
