The Elusive Progressive majority

The latest issue of the Economists points out that how elusive demographic changes can affect presidential elections. It says that by the year of 2050, the white is no longer the majority of U.S. population. The Latino share of population will double from 15% to 30%, African-American and Asian-Americans will grow from 19% to 24%. Due to the trend that minorities like to vote for Democrats, it is a bad news for the Republicans for sure. Immigrations not only affect the economic aspect of lives, surely political aspects too.
