I'm not sure the rest of the council agrees with the sentiment or moving forward without the federal government's, eh, approval isn't the right word. Acquiescence? Apathy? Yes, apathy. Councilmember Phil Mendelsohn comes to mind immediately as standing opposed in the past.
But now the recently re-elected Mayor Bowser is putting together her own legislation to bring to the council, and she's got more clout than Grosso, obvi. I watch Game of Thrones, I know how politics works, we have to kidnap somebody's brother and cut off their ding dong to make any progress. Send a raven to Blackwater Bay!
What it looks like to little old moi is that if DC government says, yes, we're gonna move forward with sales and tax even if Congress says not to, the real risk isn't to the mayor & council any more (they really for real did get threatened with jail when they implemented Initiative 71), it will be to companies that operate next door to federal law enforcement. Of course, the process of deciding how many licenses will be awarded and who gets 'em is gonna take a while, it could be a couple years before anyone is actually breaking the law. And companies are gonna buy up those licenses anyway, you better believe it.
Basically what we're looking at here is, if approved, DC gets a two year jumpstart on implementing a tax and sales program in anticipation of a Democrat in the White House. This is my expert analysis and you can tell I'm an expert because I have my own website. They don't just hand those out to anybody, you know! I mean, Gentleman Toker does. And I'm Cliff Biffington.
