    Your subroutine will accept "AK\n" as a state. Fixing that takes it to 125. But I can beat that with the following 122 character solution (which is what I was trying to figure out when I posted my first):
    sub state{ $_[0]=~/^\w\w\z/&&grep/$_[0]/,'WVTNHINMSCORIDCAKSDE WIALAR MNCTX NVAZ' +,'FLGAILKTKYMAMDMEMIMOMTNDNENJNYOHOKPAUTWAWY'=~/../g }
    OTOH I can improve your idea down to 119:
    sub state { pop=~/^([CGILPVW]A|[CKUV]T|[HRW]I|A[KLRZ]|CO|DC|DE|FL|I[DLN]|KS|KY|M[A +DEINOST]|N[CDEHJMVY]|O[HKR]|SC|SD|TN|TX|WV|WY)\z/ }
      Your first one can go down to 121:
      sub state{ grep$_[0]eq$_,'WVTNHINMSCORIDCAKSDE WIALAR MNCTX NVAZ'=~/(?=(\w\w))/ +g,'FLGAILKTKYMAMDMEMIMOMTNDNENJNYOHOKPAUTWAWY'=~/../g }
      ... or you could have just taken the easy route by converting the && into an &.

    And 2 characters less by group the first letters too:

    sub state { pop=~/^(A[KLRZ]|C[AOT]|D[CE]|I[ADLN]|K[STY]|M[ADEINOST]|N[CDEHJMVY +]|O[HKR]|S[CD]|T[NX]|V[AT]|[GLP]A|[HR]I|FL|UT|W[AIVY])$/ }
