Ralph Nader is right when he says that Americans deserve better than the two-party system (“Break up the two-party tyranny,’’ Opinion, Feb. 9). But considering Michael Bloomberg’s strong support for unconstitutional stop-and-frisk policing, and his opposition to measures like Dodd-Frank, how many Democrats beyond the urban ivory-tower elite will really turn out to support him? And on the Republican side, who would be expected to vote for him, given that his policies on guns and unhealthy food are even further to the left than most Democrats?

A successful Bloomberg candidacy might seem plausible in concept, but in reality it would be about as likely as Nader’s to break the two-party tyranny. And, like Nader’s, it could increase the chances of a Republican winning the election.
