[T]he United States is a much different country demographically than it was in 1994. A decade and a half ago, over three quarters of Americans were white. That number has dropped to just over 60% now and is on the way to falling below 50% by the midcentury. In particular, the percentage of Latinos in the U.S. population has nearly doubled (from about 9% to 16%) over the same period. In addition, half of a new generation-Millennials (born 1982-2003), the largest and most diverse generation in American history-has joined the electorate.
All of these changes have worked to the advantage of the Democratic Party and are should continue to do so in the future. In NDN's February survey of the 21st century American electorate, Millennials identified as Democrats over Republicans by a 2:1 margin (42% vs. 21%) and non-Caucasians did so by over 4:1 (57% vs. 14%). Women also strongly identified as Democrats (44% vs. 24% Republicans). By the way, the other half of the Millennial Generation, all those now under 18, already live in a world where whites are in the minority, promising an even larger Democratic edge in the future.
At least in part as a result of these major demographic changes, the Democratic Party now holds a clear lead among voters in party identification, something it did not have in 1994. In the most recent Pew national survey (pdf) released earlier this week, the Democrats enjoy a nine-percentage edge over the Republicans in party ID (45% vs. 36%). In 1994, the two parties were tied at 44% each and in 1995, the year after the GOP won control of Congress, more Americans identified with or leaned to the Republican Party than the Democrats (46% vs. 43%).
Oh, and voters still hate Republicans.
