dan chris walt -- host: daniel griswold serves as the trade immigration project codirector at the mercatus center and is joining us to talk about issues related to the border. good morning. mr. gaffney: good morning -- guest: good morning. host: what is the long-term and short-term impact if the border should be close? guest: huge for tens of millions of americans. new mexico is our number three trading partner and number two market for u.s. exports. there is $1.5 billion a day in goods crossing the border. 15,000 trucks a day crossing the border. i have seen them lined up. half a million people cross the border every day legally to work, to shop, to visit family. if the border was shut down it would be devastating for border communities. like laredo and el paso. but it would affect all of us. mexico is a major source of not only manufactured goods. prices would spike for cars, fresh produce -- we get a lot of it from mexico, particularly avocados, tomatoes cucumbers. , more importantly, for american production and supply chains and nowhere more important than the u.s. auto industry. 25 ye
