For example, in “Federalist No. 10,” James Madison wrote about his fear of the power of “faction,” by which he meant strong partisanship or group interest that “inflamed [men] with mutual animosity” and made them forget about the common good. He thought that the vastness of the United States might offer some protection from the ravages of factionalism, because it would be hard for anyone to spread outrage over such a large distance. Madison presumed that factious or divisive leaders “may kindle a flame within their particular States, but will be unable to spread a general conflagration through the other States.” The Constitution included mechanisms to slow things down, let passions cool, and encourage reflection and deliberation.
