Considering we have been through immigration reform before, I have to ask what may have changed yet again?
I must assume Republican business donors in the fence building business did not contribute as heavily as Republican business donors in agri-business. Agri-business can not only get its crops picked for less, but it can then share in the profit of the food stamp hustle for its underpaid immigrant lettuce pickers so it can sell its products sold at a profit.
Those fence builders will have to come up with a sweeter deal for the GOPe if they really want to make some money.
They are inherently at a disadvantage. You can only build a fence once. Food stamps are a recurring revenue source. $200 per person per month multiplied over tens of millions is a lot of cabbage - tens of billions a year in sales.
