Sen. Barack Obama won presidential nominating contests in three more states Saturday and all but wiped out Sen. Hillary Clinton's overall lead in the delegate count.
In the Republican race, former Arkansas Gov. Mike Huckabee won two states, keeping him in the picture despite Arizona Sen. John McCain's large delegate lead.
McCain, the GOP frontrunner, was declared the winner in the Republican caucuses in Washington state, which allocate half the state party's delegates.
Huckabee narrowly won the Louisiana primary, but he will have to have to wait for a convention in that state to allocate the delegates.
Huckabee dominated in the Kansas caucuses; he won all 36 delegates at stake, thanks to the support of social conservatives.
Mathematically speaking, it's nearly impossible for Huckabee to catch up with McCain in the delegate count. But lately Huckabee has been telling crowds that he didn't major in math, he majored in "miracles."
On the Democratic side, Obama won the Louisiana primary, but it was his most racially polarized victory to date. Almost 90 percent of African Americans backed Obama, while more than two-thirds of white voters cast a ballot for Clinton.
In the caucus states of Nebraska and Washington, fewer people took part, but Obama's victories seemed more broadly based.
In both of those states, Obama supporters overran the local caucus meetings, outnumbering Clinton supporters two-to-one.
