“They have to cluster around something,” said Meyer, whose book, “The Politics of Protest,” is focused on political movements. “Even if the first people that called for the movement are not making demands, other people are going to start using their name and making them.”
Vice President Joe Biden waits to conduct a mock swearing-in ceremony with Sen. Brian Schatz, D-Hawaii, in the Capitol's Old Senate Chamber, December 2, 2014. Schatz was sworn in to serve the remainder of his term since he was appointed to the seat after Sen. Daniel Inouye, D-Hawaii, passed away.
