As much as I detest Rob Ford, I cannot get too excited about this and I urge everyone to exercise caution.
All we have so far is an anecdotal account of a video (with no duplicates!) that may not still exist.
We also have a mayor who has managed to dodge punishment mainly because his enemies pounced when the evidence they had was circumstantial or so weak that it could be thrown out in appeal.
And speaking about "appeal", don't underestimate how dogged and fanatical the remaining 25% of Torontonians who represent his fanbase are. These people will not suddenly jump ship even if he did smoke crack with known criminals and was caught saying overtly homophobic, racist and derogatory slurs. These people don't vote based on their principles; they vote because they slavishly adhere to a cult of personality. It's like cheering for a sports team that you know sucks and plays dirty. You do it because you are a fan. He is also a man that would probably not resign under any circumstance.
I also think there is a significant share of the population - perhaps 50-60% - who won't be compelled to vote in the next municipal election no matter what Rob Ford does. In fact, I think this whole disaster will make them wash their hands of municipal politics even more.
We cannot rely on Rob Ford to be unseated by the court of popular opinion. We have to rely on Rob Ford being unseated by the court of law, and right now the evidence that we have is only slightly more credible than an 8 mm tape of Bigfoot.
