You obviously didn’t see the link I provided earlier. When a drug including alcohol gets legalized, the mafia consolidates and secures it distribution area and operations. they no longer have to risk battles with law enforcement, the field is clear and they are free to profit and pursue other criminal activity such as prostitution and extortion.
Here is the link on McCain again:

Note in this link that the original mafia from the Prohibition area is now legitimate and they have legitimate power. They are the ones that control McCain ultimately. Ever wonder how a moron like Megan McCain gets publicity for her idiocy, how she gets invited on TV etc.? She has the mob behind her indirectly through her mother.
So when we give the keys to legalized drug trade to the Columbian Cartels who are the ones behind the Mexican madness, we invite them in so they can place their people in our elected offices, we invite them in to run other crime operations with a beachfront in legalized marijuana, which they will lace with addictive additives just as the tobacco companies do to cigarettes, and they will also run meth, crack and heroin.
They will also pour money into gun control legislation, political campaigns that elect their people who are programmed to take away your rights.
Remember that Pablo Escobar was so wealthy in Columbia that he was funding a means to procure nuclear weapons to be used against the USA. These are the kinds of people you will be letting in the door, they types that hire drug crazed assassins that sever off heads of innocents to send a message. It is terrorism.
No the drug lords will not lose their businesses, they will expand them, they will become the next Phillip-Morris.
Your link does not support your generalizations - it shows only that a single local mob branch in Arizona bought into the legal alcohol business when Prohibition ended. There have probably been a handful of other such cases ... but there's no evidence whatsoever that the mob is a major player in the alcohol trade today.
(Just curious: Do you agree with your source's characterization of 'the “fix” that made George W. Bush president in a rightly disputed election'?)
