The April 28 Los Angeles Times carries this letter from UCLA Political Scientist Thomas Schwartz, about California’s new “top-two” election system. Schwartz is a specialist in social choice theory and mathematical political science. He is the author of “The Logic of Collective Choice” and “The Art of Logical Reasoning.”
The link goes to all the letters published that day. Professor Schwartz’ letter is the second one down. The letter also chides the Los Angeles Times for telling its readers, in an editorial on April 25, that the top-two system is the same system as the non-partisan system used by all California cities and counties for elections for their own officials.
