Why drug allegations ring true even without the video

So there is a ton of speculation out there about the existence of the Rob Ford crack video. Ford Nation supporters are claiming that it must not exist, blah blah blah. Because apparently despite the fact that Rob Ford is a proven liar (see here) for some reason it is more believable that a guy who works for Gawker, a US website from New York who has had no interest in Toronto or the mayor previous to this, is collaborating with two Toronto Star journalists to bring the mayor down and fabricate this story. Despite the fact that TorStar and Gawker have both said they have seen the video, had an argument about whose story it was and generally agree on all of the details of the film, Ford Nation has their heads so far buried in the sand that it can not be true.

Well people, here's a list of reasons why this story is so believable to people who don't blindly support the craptastic Mayor of Toronto.

The DUI and drug possession charge from Florida that he denied and than later admitted to.

The domestic assault charge

The phone call where he is recorded telling someone he will get Oxycontin for them.

The call by his MIL to the police about him threatening to kidnap his children "report that the mayor had been drinking and was taking his children to Florida against the wishes of his wife, Renata."

The escalation of strange behaviour this year alone:
The Sarah Thomson sexual assault story
This picture of him very obviously inebriated:

The story about him being asked to leave the gala
The fact that he ran out of a meeting to put magnets on cars unexpectedly

The firing of Chief of Staff Mark Towhey for allegedly telling him to get help

The former press secretary who wrote here that his staff has previously asked him to get help.

With all of this, how can someone argue that Mayor Ford doesn't have a substance abuse problem?? And how is it believable that all of this is made up; that his former press secretary, an ex rival mayor candidate, three journalists, multiple newspapers (the sun was the one that reported the asked to go to rehab story) are all working to bring him down for personal reasons. The previous lies and dui. It's just all way too much to sweep under the rug.

People need to do him a favour and stop justifying this behaviour and stop jumping on conspiracy theories when it is so obvious that the mayor needs help.
