For a while now, I’ve written about how the demographic increase in the size of the Latino American and Asian American populations will inevitably also lead to increased political, economic, and cultural power and influence as well. I also hypothesize that one example of this burgeoning political power was how Latinos and Asians voted overwhelmingly for Barack Obama in the presidential election and as a result, helped to put him over the top.

In other words, Latino and Asian American voters are becoming increasingly important as voting blocs — a sizable constituency group that, if mobilized to voter overwhelmingly for a particular candidate, can make the difference between victory and defeat in a close election. For years, groups such as African Americans, Jewish Americans, and “NASCAR dads” have been important voting blocs.

To reinforce this notion of the increasing political power of Latinos and Asian Americans, as first mentioned by Seth Hoy at the Immigration Impact blog, the Census Bureau has just released detailed voter data from the 2008 election and among other things, they show:

• Latinos represented 7.4% of all Americans who voted in the 2008 election (about 9,745,000 out of 131,144,000 total voters). This represents an increase from being 5.4% (about 5,934,000) of all voters in the 2000 election.
• Asian Americans represented 2.8% of all Americans who voted in the 2008 election (about 3,627,000 out of 131,144,000 total voters). This represents an increase from being 1.8% (2,045,000) of all voters in 2000.
• Non-Hispanic Blacks comprised 12.3% of all voters in the 2008 election, an increase from 11.5% in the 2000 election.
• Conversely, non-Hispanic Whites made up 76.3% of all voters in 2008, a decline from 80.7% in 2000.

The data comparisons between 2000 and 2008 clearly show that Latinos and Asian Americans (and to a slightly lesser extent African Americans) comprise an ever-increasing proportion of the American electorate. Just as important, their power as a voting bloc are increasingly becoming evident as well, as noted by the following quote from the Immigration Impact blog post:

In Indiana, Obama won by roughly 26,000 votes, and received the votes of nearly 24,000 more Latino New Americans than John McCain. Similarly, in North Carolina, Obama won by approximately 14,000 votes, yet received the votes of nearly 26,000 more Latino New Americans than McCain.

We should note that Whites are still the largest racial voting group by far. Nonetheless, the rise of Latinos and Asian American is likely to become even more pronounced as both both groups continue to increase in population size, particularly among those who become naturalized citizens and the second generation (the U.S.-born).

The other interesting trend to note is data that shows Latino and Asian American voters are increasingly voting Democratic as well.

With these demographic and cultural shifts in mind, the fundamental nature of the American political landscape is likely to continue to change for generations to come.
