This is from today's Wall Street Journal:
The longer term danger is that the GOP is sending a message to Latinos that it doesn't want them in the party. And if that message sticks, Republicans could put themselves back in minority party status for a generation or more. Hispanics are the largest ethnic minority in the country, and their voting numbers continue to grow. Hispanics were estimated to be 8% of the electorate in 2006, compared with 6% in 2004 and 5.5% in 2000. Census data show that the number of Latino voters could rise to 10% or more by 2008. The demographic reality is that the GOP can't be a majority party with Anglo-Saxon votes alone.
