A new report shows the U.S. Latino voting block increased in the last four years. The growth is in the millions. Since 2008, the number of Latino registered voters increased by four million. The Pew Hispanic Center analyzed the most recent U.S. Census voter registration data. It found that more than 24 million Latinos are eligible to vote in the 2012 Presidential election. Despite the increase, the report also shows Latino voter turnout continues to lag behind other ethnic groups. In 2008 only 50 percent of Latino registered voters cast their ballots, compared to 65 percent of African American voters and 66 percent of white voters.
