She's saying that Rob Ford doesn't return all the phone calls that he claims to. I don't know why reporters haven't debunked his claims a long time ago.
Instead they do as the columnist does and continue to pass them on as truth, untested:
I don't see how we know he is continuously on his cell phone, returning calls, other than him saying it, and reporters unquestioningly repeating it. The video, perhaps not effectively, attempts to simply point out that the claims are not all true. Ford scores a lot of points off this myth.
He has been ineffective not because he's busy checking out TCHousing or returning phone calls, neither which he does with the frequency that he or the writer here claim he does, but because he has substance abuse issues that make it difficult for him to get into work before noon, or focus while he's there, and because he's spending time hanging out in bushes near the high school downing bottles of vodka with his drug dealer.
