Suburbia is 50 % of the vote...Big cities are only 30 % of the vote.

Do you have a source for that?

The Impermanent Republican Majority

By winning the urban vote — which made up 30 percent of the electorate in 2008 – in such a lopsided manner, Democrats could afford to lose rural areas, which were 21 percent of the overall vote. When Sarah Palin talked on the campaign trail about the “real America,” she was referring to a shrinking one.

The biggest prize is the suburbs, where half of all voters live.

I've seen a similar breakdown elsewhere.
