In Mexico they have a north-conservative/south-liberal divide.
You should use the country-appropriate terminology. As pretty much everywhere outside the US, Mexican leftists would be horrified if you were to call them liberal. "Liberal" in this context means pro-market, anti-sociallist, technocratic, though, possibly relatively secular. None of the leftists in Mexico are "liberals" (and not many of the rightists are, for that matter).
I guess, in Mexico the division is:
1. pro-business conserative/old-time priista North
2. ultra-conservative right-wing Catholic North-Central heartland (Bajio),
3. leftist/populist South
4. leftist metropolitan Mexico City
5. highly mixed South-Central area around Mexico City (with rightist and leftist areas interspersed in a chess-board fashion: mostly conservative cities and leftist/populist smaller towns and country areas)
6. ambiguous-to-conservative Yucatan peninsula.
In terms of urban/rural divide it is also non-monotonic. In general you have:
1. Leftist giant Mexico City
2. Right-wing conservative almost all other major cities
3. Leftist and/or populist smaller towns and rural areas
