CJ Werleman's just published Atheists Can't Be Republicans.
That atheists are secularists is one reason why atheists can’t be member of today’s Republican Party.
The Grand Old Party (GOP) is ... a theocratic sponsor,...
Atheists can’t be Republicans because the economic and social policies of the Republican Party have been proven abjectly false and dangerous. Much in the same way religion is false and dangerous. In other words, atheists who cling onto modern U.S. conservative ideology are hanging onto ideas that have either been proven mythical at worse or remain unproven at best. If atheists applied the same litmus test to their political ideology as they do to theology, then clearly an atheist cannot be a Republican.
Atheists are the fastest growing minority in the country. We now have the critical mass to shape elections and policy. Were atheists able to establish a monolithic political demographic, one that is based on proven economic and social policies, then our potential political power would translate into saving this country from the clutches of the American Taliban and Wall Street.

... I have come in contact with as many idiot atheists as I have with idiot Christians, Jews, and Muslims.
