Explain how the example paragraph above illustrates bandwagon fallacy and why that fallacy makes the argument weak.

"phoenix is a city whose time has come. the inner city is being restored, the university is moving downtown, and property values are on the rise. but we haven't quite arrived. any downtown metropolis worth its salt has a commuter rail system. just look at new york, chicago, seattle, and san francisco. don't leave phoenix behind. vote "yes" for light rail."
