Here's a chart breaking down New York Times exit poll results from the mayoral election.
What sticks out to us is not so much that 3 percent of voters rated transportation as the "one issue" that mattered most to them, since many who participated could care a great deal about transportation and you wouldn't know it.

Obviously, despite the low level of interest indicated here, transportation matters. Otherwise pols wouldn't drone on about the MTA ad nauseam. But what do these numbers tell you?
