Obama's Hispanic problem

McClatchy,

Barack Obama has picked up support from nearly all the Hispanic voters who voted for rival Hillary Clinton in the Democratic primaries, giving him a nearly three-to-one lead over Republican John McCain among Hispanics, a poll released Thursday shows.

The Pew Hispanic Center survey found Obama with 66 percent of the Hispanic vote to McCain's 23 percent.

Given the circumstances of both campaigns, why isn't Obama's lead 10 to 1? How can Obama hope to ever be President if any Hispanic would ever vote for McCain.
