Kind of depends on what comes after the state abbreviation, but listfirst
with a space delimiter is certainly one way to go, as long as you know there
will always be a space following the state.

Easiest way to find out is to test. ;-) But yes, that will give you MO.

That's where a regex comes in, and this could handle the length check as
well. This tests for alphabetic characters:
<cfset ok = REFind("[[:alpha:]]", statematch) />
This would also handle the length bit:
<cfset ok = REFind("^[a-zA-Z]{2}$", statematch) />
So you could do:
<cfif REFind("^[a-zA-Z]{2}$", statematch)>
<!--- state is ok --->
<cfelse>
