I find it interesting that in every subway poll I ever created, subway won by a large margin over LRT, but in this poll it's split about 50-50, whereas you'd expect a similar advantage to subway. SOS's plan is really just the sum total of all the polls I conducted on this site over the years (Eglinton, SRT, Sheppard) so I admit I'm surprised. But it's only been a day. So we'll see.
Maybe the answer is: any particular subway expansion is affordable, but expanding the network isn't? I'm not sure. But I still think there are real savings to be had by having continual subway expansion rathe than the one-offs we've been doing recently.
