Obama Pimping it to the White House

Obama and Huckabee have done well in caucus states like Iowa, where grass-roots efforts are more likely to have greater influence.

Obama also picked up a boost in Washington with the endorsement of the state's governor, Christine Gregoire.

On the Republican side, McCain and Huckabee were running a close race for first in Washington. Texas Rep. Ron Paul was trailing them by about 5 percentage points.

Saturday's Republican contests in Kansas, Louisiana and Washington could predict whether the party will line up behind McCain as its candidate or provide Huckabee with an opportunity to zing the presumptive nominee.

"People across America are gravitating toward our campaign and realizing that there is still a choice. And that's what we've said all along, that this race is far from being over," Huckabee said after the results came in.
