Crack head president - a very unjustified comment 007, and here is an explanation...
If people need a passport to cross over, and in order to receive a passport you have to fill out forms, thus giving info for a simple investigation. Because there are people who cross the borders who are not really allowed to, this would help the influx of some criminals and terror cell sympathizers. I saw on channel 7 in Buffalo that it will be like 96$ for a passport. If paying money for an ID that tells the border patrol I'm trusted and OK'd...then screw it gimme one, but to say its an idea unjustified by a crack head president, well I would hope you realize who is looking out for you.
As far as commerce, this may be a tricky issue unless the feds make passports cheaper for people living in areas around the border, Buffalo, Detroit and Seattle for example. If people have to endure an extra 100$ they might continue to shop and vacation on their home turf, thats not good for Buffalo.
