Wise? When you have a herd of 5,000 migrants a day coming across your state....folks tend to notice things. I would imagine that folks in AZ will notice and start bus events to continue delivering migrants to sanctuary cities.
The development? I think several big city mayor's have given 'hell' to the handlers and demanded something to change.
Oh, and this wall work? I'd guess there's a minimum of 6 months of work required. I should also note...the wall business so far has proven marginally to be effective. Those buses from Texas? I would imagine they will keep operating.
