Loading the ccrypto module: a personal module written in C interfaced with Python.
The only function used here is RS_substitution, a MASC solver using a simulated annealing algorithm.

For a Python version of this function see http://bribes.org/crypto/substitution_mono.html (in French, sorry).

Spanish words appear. It seems that they are separated by S. Let's check this hypothesis:

In [10]:
_[2].replace('S', ' ')
Out[10]:
'NOT LOT REPRETENDANDET HEL PUEBLO HE LA NACION ARFENDINA REUNIHOT EN CONFRETO FENERAL CONTDIDUYENDE POR VOLUNDAH Y ELECCION HE LAT PROVINCIAT QUE LA COMPONEN EN CUMPLIMIENDO HE PACDOT PREEXITDENDET CON EL OBJEDO HE CONTDIDUIR LA UNION NACIONAL AGIANKAR LA JUTDICIA CONTOLIHAR LA PAK INDERIOR PROVEER A LA HEGENTA COMUN PROMOVER EL BIENETDAR FENERAL Y ATEFURAR LOT BENEGICIOT HE LA LIBERDAH PARA NOTODROT PARA NUETDRA POTDERIHAH Y PARA DOHOT LOT WOMBRET HEL MUNHO QUE QUIERAN WABIDAR EN EL TUELO ARFENDINO INVOCANHO LA PRODECCION HE HIOT GUENDE HE DOHA RAKON Y JUTDICIA ORHENAMOT HECREDAMOT Y ETDABLECEMOT ETDA CONTDIDUCION PARA LA NACION ARFENDINA'

The hypothesis is plausible.
Since the decryption alphabet is

  ABCDEFGHIJKLMNOPQRSTUVWXYZ
  NOTSLREPDAHUBCIFYVQMXJGKWZ

the letter S of the solution corresponds to the letter D of the crypto.
We replace D by _ in the crypto.

In [11]:
t = t.replace('D', '_')
print(t)
