Or 105:

print

/^..\z/&("MNCAKSCOHINMOKTNVALARIDCTX

ORIL"=~/$_/|
/FL|IA|KY|M[ADEIST]|N[DEHJY]|PA|[UV]T|W[AIVY]/)

for qw(AK AL AR AZ CA CO CT DC DE FL GA HI IA ID IL IN KS
       KT KY LA MA MD ME MI MN MO MS MT NC ND NE NH NJ NM
       NV NY OH OK OR PA RI SC SD TN TX UT VA VT WA WI WV
       WY MY MNC .* ), " SD", "AZ\n"

(Dropping the inner parens around the or-chain and disregarding the state of NN which is not being honored today.)

OOPSDATE: Yep, matches if $_='.*' (see runriq immediately below and slightly to the right).  It needs /\Q$_/, as so often happens, which defeats the character savings.  I was looking at the \w as avoiding matching the spaces (which it also does).    (Oh, and thanks runriq and I'm sorry too!)

Sorry, but your expression makes '.*' an honorary state :-)

That's why dws uses '\w\w' instead of '..' in his answer.
