The Espionage Act- Could It Happen Today?

In 1917, the U.S. government passed the Espionage Act to limit opposition to WWI. While the intention was good, it severely limited peoples' right to free speech. History has shown that in certain situations, the citizens of the United States have been willing to suspend or give up certain rights guaranteed by the U.S. Constitution...why do you think that is? Do you think a law like the Espionage Act could be passed in the United States today? Why or why not?
