Barring a MASSIVE policy change on the part of republicans
Hilldawg will clean up in 2016 and by 2020 demographics will have turned Texas into a swing state, 2024 it will be blue. No way the republicans ever muster 270 electoral votes with texas up in the air. Also, 2 terms for Obama and 1-2 for Hillary will make the courts Blue for the next half century.
Conservative parties have a history of dying out and unless the republicans radically change their platform and out lib the dems (kind of what the dems did to the republicans early in the century), the first half of this century will see democratic dominance similar to 1800-1836.
HTH.
