Compare areas where each has had a lot of influence. Dems own education and Reps have had more influence in military. Of course education has become a disaster and military functions reasonably well. You can see the same division looking at states. Big Dem states like California and New York are evolving into failed state status. History isn't kind to Dems either - having been party of slaveholders and them Jim Crow for almost 100 years. Heck even FDR opposed anti-lynching laws the GOP was for. The vote for civil rights act of 1964 (based on things Eisenhower tried to get done by Dems voted down) had more Reps than Dems voting for it. Dems tend to be irrational where reality is concerned - hence their inclination to support US enemies (Soviet Union, China, Radical Islamists etc) while throwing banana peels under Uncle Sam's feet. All the bag guys are happiest when Dem becomes POTUS.
