According to a new survey, President Barack Obama continues to receive high marks from both African-American and Latino voters. His numbers among Latinos are down slightly from 2008: Then, he received the votes of 67 percent of Latinos according to exit polls, but the new survey only shows him taking 64 percent. That downturn, however, comes before what you can expect will be some hard-hitting ads about the increasingly virulent anti-immigration stances of the various GOP candidates. Key states such as Colorado, Nevada, Arizona, New Mexico, North Carolina and Florida may all depend on how well Obama does among Latinos.
