The reason the other mayors are on board is because they have been cut in on the action as they are slated to receive some of the tax revenue.
It is laughable that Mayor Caldwell is quoted in saying " I remain hopeful that common sense is going to prevail".  This from a man who obviously lacks common sense regarding this disaster of a rail project which is going to not only
bankrupt the City but eventually the entire state.   It would be very funny were it not so tragic.   There should not be a special session called by Ige if this whole tax scheme collapses as time runs out for this legislative session.
There needs to be a pause and we need to see what the Feds and Trump decide and a new proposal for rail needs to be put on the table.  Stop it at the Stadium for now.
There has been very few if any rail projects like this that were built all at once.  Most projects of this kind are built in segments and changes are made as problems in operation/maintenance etc are discovered.
