Robert Farley, in a post about Kentucky politics:

Apart for the electoral stupidity, the notion that Louisville isn't the "real Kentucky" rankles in the same way as Sarah Palin's assertions about "Real America." Dividing the country between the pure heartland and the decadent urban cesspools has been a Republican electoral tactic since at least the 1960s, and it still carries a heavy stench of exclusion. One out of every six citizens of Kentucky lives in Louisville, and they're just as real as anyone else in the state. More importantly, their votes count just as much; there is no Electoral College for the US Senate in Kentucky. I detest the notion that rural voters are somehow more authentic than urban voters, and this seems to be what the Mongiardo folks are pushing in order to explain away a weak fundraising quarter.

The thing is, that tactic is less effective than it used to be as there seems to be an inverse ration between the power of divisive politics and the size of cities: as cities get bigger (which they are doing) the power of trying to get people to come together against the urbanites becomes weaker. It once made sense to rally the various suburbs together by creating a common foe but not anymore. A successful politician has to look toward unity instead of division to get elected.
