(CNN) – The latest national survey of likely Latino voters shows President Barack Obama retaining a big lead over rival Mitt Romney in the key voting demographic, matching the level of support he received from Latinos in 2008.

The poll also showed a majority of Latinos said the economy was a more important issue than immigration, and indicated enthusiasm among Latinos is lower than it is among non-Latino whites.

Obama enjoys the backing of 70% of likely Latino voters, according to the CNN/ORC International survey, slightly higher than the 67% of Latinos who voted for him in 2008. Republican nominee John McCain garnered 31% of the 2008 Latino vote. In 2004, 53% of Latinos went for the Democratic nominee John Kerry over the 44% who went for President George W. Bush, according to national exit polls.
