The Green Party ended its four-day national convention in Houston, Texas, yesterday with resounding endorsements of their standard-bearers in the general election—physician Jill Stein for president, and human-rights activist Ajamu Baraka for vice president. The convention was one of the latest to be held in the current political season, just three months before Election Day. But the newly launched Stein-Baraka ticket has deep roots in nonmainstream activism and politics, Stein said; their nominations formally gave them permission to represent the party and its constituent base in an election in which an alternative to the duopoly is urgently needed.
