The new ABC/Washington Post national poll shows a tight race between Hillary Clinton and Barack Obama. Here are the numbers, compared to the previous poll from three weeks ago:

Clinton 47% (+5)
Obama 43% (+6)

John Edwards was at 11% in the last poll, an indication that his support may be breaking fairly even between two remaining candidates in the country as a whole — though the breakdowns have also seemed to vary from state to state in other polls.

On the Republican side, it's a different story. John McCain is way ahead, and appears to have picked up virtually all of Rudy Giuliani's past support:

McCain 48% (+20)
Romney 24% (+5)
Huckabee 20% (-4)
Paul 7% (+4)
