Via FOXNews.com: "Dozens of California lawmakers are pushing to make their state the first in the nation to impose an across-the-board boycott on Arizona over its immigration law" If these lawmakers succeed, they will enter into questionable legal ground. The Constitution's commerce clause was designed to prevent states from enacting protectionist policies that would impede commerce with, and competition from, other states. In 1824, the Supreme Court overturned a New York law that granted a monopoly to a local steam boat operator, Aaron Ogden. Ogden operated a ferry service between New York and New Jersey which faced direct competition from Thomas Gibbons.
