Nick Gillespie on NBC Nightly News tonight, 6:30 p.m.

Reason.com Editor In Chief Nick Gillespie will appear tonight on NBC's Nightly News. 

Topic: New York City Mayor Michael Bloomberg is obsessed with cup size. 

The Big Apple chief executive is moving to ban large-sized sodas in the city so nice they ticket you twice for sitting on a milk crate. 

The proposal is finding favor only with the soda-is-murder voting bloc.

Even the liberal Daily Beast says the ban is a thirsty-two ouncer too far. Columnist Trevor Butterworth calls the mayor a "walking advertisement for libertarianism." 

But even Mrs. Butterworth can't escape the dead hand of trendy, feel-good micromanagement. 

And Bloomberg always gets what he wants. 

Can a town without a 1.2-liter Super Big Gulp truly be called great?
