Repealing this will be difficult, because you have a small focused organization supporting it, and you have a large, diffuse, and distractible public.

And those maritime guys are hardcore union guys, which will make Democratic support a given.

The only reason it has a chance to pass now is because the repeal may reduce costs for millions of consumers. If it's hurting home heating oil customers in New England then the NE delegation may get behind it. That'll put them against every state that's contiguous to water (including inland waterways). I'd put the chance of it passing at 15% unless something exciting happens.
