I can correct you here. Ease of access had nothing to do with it at all. He knew from day 1 that even without a Ford in the race, Ward 2 was going to be a challenge for him. He knew that he had no name recognition and that he would never, ever get the support of the Fords given his politics (and, to be frank, his skin colour. Andray got a LOT of racist stuff thrown his way that he didn't talk about in the media). Plus, the spectre of a Ford entering/re-entering the race was always there. Rumours about Mikey running swirled for months, and nobody believed that Doug wouldn't run when Andray signed his nomination papers.
Ward 5 and 6 were never considerations for Andray. He was raised in community housing in Ward 2. It was always where he was going to run. His politics coincided significantly more with the needs of Ward 2 than of 5 or 6. Ward 5 might have been more winnable, but that's neither here nor there. He wouldn't have been a good fit for Ward 5 and he'll be the first to tell you that. He doesn't have strong ties to either of them - his heart is in Rexdale. To win a seat because it's easier is opportunism at best and carpetbagging at worst.
Futher, Larocque would not have made a race of it in Ward 3, that I can tell you. First off, he would have been going up against Stephen Holyday, who has the family juggernaut name. Annette Hutcheon was first out of the gate on day one and she covered the ward in literature and flyers. John Moskalyk and Greg Comeau had federal-level endorsements. George Bauk is a well-known realtor who was running to raise his profile, and Peter Fenech brought up the progressive side. With respect to Luke, he has no name value and no significant experience, and his platform did nothing stronger than anyone else. At best, he would have entered a crowded field and maybe taken some votes from Comeau.
In Ward 4, he'd be in just as tough against John Campbell and Niels Christensen. Campbell was the Chair of the TDSB and Christensen has a crazy resume, led the Save Humbertown campaign, and is the president of the Humber Valley Village Residents' Association. Plus, Stockwell.
