McCain, Obama in final push for White House

Barack Obama said, "Nevada, at this moment in this election, we have a chance to do more than just beat back this kind of politics in this particular election. We can end it, once and for all. We can prove that the one thing more powerful than that kind of politics is the will and the determination of the American people to change this country. Yes, we can."

Obama is leading in national and key state polls against McCain.

And Nevada is one of several states Obama hopes to snag from the Republican column.

John McCain once risked his career on an immigration reform bill that was embraced by Hispanics. But he is now struggling to win those same voters in the state of Nevada.

The swing state has a precious five electoral college votes up for grabs. They could potentially be a deciding factor for either presidential candidate, hoping to gain the 270 votes needed to claim the White House.
