Realistically speaking I think that the only vacancy on council will be Lucas. Of all runner ups Helps has the biggest chance, I think.
I'm amazed that more people don't see Fortin for the bully he is. If Lucas is vulnerable, it's because he's no longer part of Dean's "team," and if he's no longer part of the team, it's because he dared to differ with Fortin on some issues. I sometimes think this council goes into camera so often (32 out of 33 meetings, according to Open Victoria) so that Fortin can keep forcing everyone back in line. That's just my sense of things after having watched him during the open parts of meetings.
