In the new ABC News/Washington Post poll (the full details of which will be released later today), Hillary leads Obama comfortably, 41% to 17%, and Giuliani leads McCain by seven points, 34% to 27%

Newsweek's new poll shows the following hypothetical head to head matchups:

Clinton 47, Giuliani 48

Obama 46, McCain 44
Obama 45, Giuliani 47
