GOP-dominated suburbs

[PoliticalShelter]

The three main factors I think that would determine how republican a suburb is, would be:

Diversity: the more diverse, the less republican it will generally be.

Religiosity: Obvisouly the higher religious affliation (particularly evangelical), the more GOP.

Urbanisation: suburbs that have a more "exurban" (less congested and more spacious) character will be more republican than those with a more "urban" character.
