Someone needs to tell The Dick that most large cities (urban areas) have majorities of Democrats, therefore of course many more democrats will be voting compared to repubs in the cities.
Even here in Texas (where the republicans try to suppress votes) our largest cities/counties (Austin, Dallas, Houston, El Paso, SanAntonio, etc) were won by Democrat Obama in the 2008 election ;)
Edited to add: There have been reports this week of The TeaParty trying to suppress Texas votes in minority polling places. I think Dick Armey is trying to take the focus off of that fact!
