Another survey is showing Barack Obama ahead of John McCain nationwide, with the ABC/Washington Post poll giving the presumptive Democratic nominee a 49%-45% lead among registered voters, and 48%-42% lead among all adults.

Other questions in the poll don't have much good news for McCain. Only 34% of respondent feel the Iraq War was worth fighting, with 63% saying it was not. If US casualties are involves, 55% of respondents want to withdraw forces from Iraq rather than maintain civil order.

The only good question for McCain involves the recent Supreme Court decision on Guantanamo detainees, with only 34% saying prisoners there should be able to challenge their detentions in civilian courts, and 61% saying they should not. As such, expect the GOP to hammer this issue.
