If the suburbs stop being so damn Republican. Also, I believe McCain got over 30% in Houston and San Antonio, so it's not like those cities provide a ridiculous margin of votes for the Democrat. And Hispanics in Texas are slightly more Republican than in most other states.
He actually got about 38% in Houston, and 42% in San Antonio. The biggest reason the Democrats do so poorly is because they are held to such low margins in the big cities that they usually dominate in.
Yeah, that was the point I was making...
