SACRAMENTO (CBS/AP) — Gov. Jerry Brown has signed a bill that would award all of California’s 55 Electoral College votes to the winner of the national popular vote in presidential elections.

The movement by a group called National Popular Vote aims to prevent a repeat of 2000, when Democrat Al Gore won the popular vote but Republican George W. Bush won the electoral vote. The group’s proposed changes would ensure the winner of the national popular vote becomes president.
