He was skewered on Saturday Night Live. Striped of his powers at city hall. And admonished by Matt Lauer. But Mayor Rob Ford’s very bad week seems to have had little impact on his approval rating.

A new poll from Forum Research puts the mayor-in-name-only holding steady at 42 per cent, which is down just slightly from two weeks ago after Ford admitted to smoking crack cocaine.

The automated phone survey of 1,049 Toronto residents was done Wednesday night — two days after Monday’s special council meeting, which essentially made Deputy Mayor Norm Kelly the chief magistrate of Toronto.

Of those surveyed, 60 per cent thought it was the right decision to transfer most of Ford’s budget, staff and authority to the deputy mayor. The same percentage of people want Ford to resign.

It’s been three weeks since police Chief Bill Blair dropped a bombshell on the city, announcing that police had recovered a video of the mayor appearing to smoke crack cocaine. Ford admitted to smoking the drug several days later and his grip on power has rapidly unraveled ever since. According to Forum, 69 per cent of people in Toronto believe the mayor has a substance abuse problem — including more than a third of his supporters.

Perhaps most interestingly, 33 per cent of respondents said they planned to vote for Ford in the next election whether he goes to rehab or not. And one fifth of those surveyed said they would support Ford for prime minister — an aspiration he reiterated last weekend to Fox News.

Since Ford took office in December 2010, Forum has tested the mayor’s approval rating more than three dozen times. On average, the mayor’s approval rating has been in the mid to low 40s throughout his term.

This most recent survey is accurate plus or minus 3 percentage points, 19 times out of 20.
