John McCain says he has earned the trust of Hispanic voters by championing an immigration reform bill that nearly killed his presidential bid. The Republican presidential candidate also says, in remarks prepared for delivery Monday in San Diego, that Democrat Barack Obama failed to take a similar stand on the politically explosive issue of illegal immigration. McCain will speak to the annual convention of the National Council of La Raza. Obama appeared before the group on Sunday, another indication of the fierce jockeying for a critical pool of voters, a quarter of them undecided in a recent poll. McCain, a senator from Arizona, saw his White House bid nearly collapse from conservatives' anger over his effort to pass comprehensive immigration reform, which opponents branded "amnesty" for millions of illegal immigrants.
