Who are those people, exactly?
I run in mostly right-wing circles (online especially), and the vast majority of people on the right seem to be opposed to the "War on Drugs" on the grounds of individual liberty. I can't imagine many on the left are in support of it - am I wrong?
I don't think it's nearly as popular as it might seem.
I think the OP is calling some these people out as hypocrites who demand "touch on crime" policies that disproportionally affect poorer communities, while they themselves break laws.
That aside, I find the hypocrisy elsewhere, namely the people who want small government but who want everyone to pay billions for mass incarceration (and raise taxes for more police) as a result of these policies.
You might run in right-wing libertarian circles, but I'd speculate that if your experience was based on the religious right you may perceive higher levels of support.
I do agree with you though, it's lost a lot of momentum over the years and now opinion seems to be that it's clung onto by law enforcement and the lobbyists of the companies who supply them because it allows for their continued militarisation and supports a significant portion of their budgets.
