How do the medium-sized cities like Mesquite, Garland, Irving and Grand Prairie vote in Presidential, Senate and Gubernatorial races? Are they like 55% GOP or 75% GOP? Do all the Democratic gains in recent years in the county come from the city of Dallas or is it also south side suburbs like Duncanville which are only plurality white?
Irving - Obama 50.6% - McCain 49.4%
Garland - Obama 46.8% - McCain 53.2%
Mesquite - Obama 50.2% - McCain 49.8%
Grand Prairie - Obama 52.1% - McCain 47.9%
I haven't looked at the precinct data for other races but I'd wager that most Democratic gains have come in the inner suburbs like Irving, Mesquite and Grand Prairie.
