That’s a ****-awful point actually.
1) Governing and Politics are two entirely different things. It’s different people doing it, has different skills required and is dependent on different circumstances.
2) It’s really just your opinion that major cities are run particularly poorly. It’s *perhaps* a bit more complicated to keep NYC or Chicago running well than a small town given the millions of ****ing people in them.
3) Most importantly, it’s just directly wrong that they are particularly good at driving the vote in cities. If they were, Dems would win basically every election unless all the people not voting in cities are the Republicans who think their votes don’t count or something.
