Evangelicals do not understand free market economies

Rick Perry of Texas is about to enter the Republican primaries for President and so we will have another Evangelical in the race. Republicans need to renew their commitment to free markets and capitalism which I postulate are libertarian versus God fearing fundamentalists who are authoritarian by nature. When a Perry or  Bachman espouse a free market solution of reduced taxes, government and regulation to add supporters to their tent they create a conflict between authoritarian and libertarian ideals which will result in poor decisions. For example Richard Nixon had no real ideology other than Republican expediency. How else can you explain his putting in wage and price controls when he was President? In spite of rabid anti communism he couldn' have been more like one, authoritarian!
