(CNN) - Latino voters are increasingly fleeing the Republican Party, exit polls show.
Two-thirds of Latino voters nationwide voted for Barack Obama, while 30 percent picked John McCain. In 2004, President Bush captured 40 percent of the Latino vote.
Watch: Latinos flock toward Obama
The advantage could prove particularly decisive in Arizona and Florida, two states CNN has yet to call. Even in McCain's home state, 61 percent of Latinos voted against him. In Florida, where Latinos picked Bush over Sen. John Kerry in 2004, Obama is carrying 57 percent of the vote.
The reason Obama is doing so well with Latinos is because they appear to disapprove of Bush's job performance more than the rest of the country. About 80 percent give the president negative marks, while 72 percent of all Americans do.
