Yes it could. Which is why I'm saying that it won't be allowed to happen.

Wal-Mart might purchases a lot of products from China. If legislation disallowed such purchases, Wal-Mart would have to reestablish manufacturing sources for products in other countries. If that happened abruptly, could it harm Wal-Mart economically?

Sabre rattling. Vote gathering. Demagoguery at its worst. It's a no-brainer that this will not happen. How do I know? Walmart exists, and it has all the clout on both sides of the fence.
