In the 2012 presidential election, which factor or factors appear to have most influenced voting choices? a. age and education level b. race and ethnicity c. education level d. wealth

At that election, political parties rely mostly on identity politics in order to draw support from the citizens. While this strategy may proven to be effective for the two elections, there are some misinformation that might damage the solidarity united states' citizens have as members of one same nation.
