(CNN) – Immigration is a key issue for Republican voters in California – a fact that is benefiting Romney, and helping keep the race close there.
Illegal immigration and the economy are roughly tied as the most important issue for California Republicans. As has been the case in some other states, McCain is beating Romney among economy voters in California by 12 points, even though Romney has been emphasizing his business background and understanding of how the economy works.
But Romney has a clear lead among voters most worried about immigration – he's beating McCain by 34 points on the issue. Illegal immigration has proven to be less of an important issue in other states, and by extension less beneficial to Romney. Romney's tough stance on the issue seems to be paying off in California.
