Not a day goes by that a leading Republican presidential hopeful doesn't reveal a level of ignorance and prejudice unprecedented in modern American politics. Today, Ben Carson, who is now running second to Donald Trump, said that Adolf Hitler's mass murder of Jews "would have been greatly diminished" had Germans been allowed to carry guns.
Whether it's Carson on guns or Muslims; Trump on Mexicans, "anchor babies," or Obama's citizenship; or almost any of the Republican candidates on abortion, gay marriage, or climate change - the leading GOP presidential candidates are reaching ever higher into loony land.
House Republicans, meanwhile, are in chaos – unable to elect a Speaker because of the right-wing know-nothings among them who want to shut down the government over the funding of Planned Parenthood and the looming debt limit.
We must face the discomforting fact that one of America's two major parties has lost its mind. How did this come about? Perhaps it's the inevitable culmination of decades of toxic bigotry and ideological paranoia spread by Rush Limbaugh and his imitators, Fox News, and right-wing hate groups - fueled and funded by the Koch brothers and other oligarchs - combined with blind rage that a black man became president - that has finally eaten away enough of the gray matter of an increasingly angry, mostly white, mostly rural, mostly male Republican base to leave us with a zombie GOP.
