mysql MySQL Trim

[Prodjex]

I have a column within my MySQL table that holds city and states for records.

The dataset looks like the following:

Clay County, AL  
Cleburne County, AL
Coffee County, AL
Colbert County, AL                    
Conecuh County, AL                   
Coosa County, AL                 
Covington County, AL

I need to just select the state name for all of the records.  Since I know this is not user input and the data is all clean/structured as above I can trim off what I don’t need with the following command:

select right(trim(cityStateField), 2);

This then returns the needed results with just the state abbreviation:

AL
AL
AL
AL
AL
AL
AL
