Well yeah, of course it was.
You see, it went like this. Rove ordered Bush to have Cheney go back in time and contact the alien overlords that would later hide their manipulating presence behind the corporate behemoth “Haliburton”.
Cheney carried the message to the alien overlords directing them to divert a comet toward earth and destroy the mega fauna and the peaceful nature loving Clovis people.
If the Clovis culture had been allowed to flourish, then the RWDB movement would never have gotten started, due to the overwhelming peaceful and nature loving influence they would spread to all peoples everywhere.
The mega fauna had to go because Rove is allergic to woolly mammoths.
Sounds reasonable to me (if I were a liberal)
