George R.R. Martin, whose novels were adapted for the HBO series "Game of Thrones," has penned an angry blog post about what he sees as "ongoing attempts at voter suppression in Ohio, Pennsylvania, Florida, Iowa, and other states where Republicans and their Teabagger allies control key seats of power."

"It is one thing to attempt to win elections," he writes. "But trying to do so by denying the most basic and important right of any American citizen to hundreds and thousands of people, on entirely spurious grounds... that goes beyond reprehensible. That is despicable."
