You said you had 20 hardcore right wingers. But most of these you have not described that way. Plus you're wrong on a bunch of them as follows:
Ward 4 John Campbell is a centrist.
Ward 5 (my ward) Justin DiCiano is centre/centre left. In his one term he voted many times with the left leaning councilors against Ford.
Ward 6 Mark Grimes at most is centre right.
Ward 7 Giorgio Mammoliti has been all over the map. But he was a Ford backer later in his career so I'll give you that one
Ward 26 Jon Burnside is a centrist like Campbell
Ward 33 Jonathan Tsao ran as a Liberal in 2020. He's left wing.
Ward 35 Michell Berardinetti is married to a former Liberal MPP and worked for two Liberal MPP's offices. Centre left.
Ward 39 Jim Karygiannis is a lifelong Liberal. He's a nutjob all right but to the left of centre.
Ward 40 Norm Kelly is a former Liberal MP he's a centrist at the most.
Ward 41 Chin Lee is a Liberal and ran under that party's nomination in the 2018 provincial election. He's centre left.
Ward 42 Neethan Shan is an NDP'er. He was a former provincial party President. He's left wing.
Ward 44 Jim Hart worked for years for councilor Ron Moeser who was basically a centrist. I don't know Hart's political leanings but I see nothing to indicate he's right wing.
You don't know your ward or former ward councilor Justin Di Ciano very well.
He served on council for 1 term from Dec 2014 - Dec 2018. Rob Ford served from Nov 2010 -Nov 2014. They were never in the same council/mayoral term together.
Please tell us how many times and on which council votes did he vote with "left leaning councilors" against Ford?
Wait you aren't required to answer that question, because we already have the answer. ZERO times.
When I look at which council members are left, center, right or any other derivative thereof, I look at their voting record. On regarding your list above, they voted with John Tory and his center-right agenda the vast, vast majority of the time.
Jon Burnside, John Campbell, Norm Kelly, Jim Hart are/were as centrist as Rob Ford was a left-wing radical.
