What we really need is more territories to be included in the boycott. Right now, it is still possible to reroute unprincipled truckers to New York, and let the ones joining the boycott take the other routes. It might be only slightly more expensive and inconvenient.

But if a few more blue cities announce solidarity with New York, and the boycott extends to those, there simply won't be enough truckers willing to deliver. That is when things will really start to bite.
