Obama starts his Hawaii vacation with a mystifyingly long list of questions unanswered about the convention that's barely two weeks away. He has no running mate, no set speaking schedule, no real sense of what protests he'll face -- and no party peace.

As Sen. Hillary Rodham Clinton hits the trail for Obama Friday in Nevada -- her first solo campaign appearance for the candidate she's endorsed -- it's time (again) to try and answer the question she famously posed two months ago: What does Hillary want?

"Advisers to Sen. Barack Obama are scrambling to reach a compromise with Sen. Hillary Rodham Clinton to appease her supporters and find roles for her and her husband," Anne E. Kornblut writes in The Washington Post.

"The back and forth with Clinton -- as well as questions about whether her husband will actively campaign for Obama after the convention -- threatens to distract attention from what Obama's backers hope will be one of the convention's central themes: change," Kornblut writes. "Planners are hoping to create an event that looks and feels different from past conventions, with more interactive components and an emphasis on the grass roots, in order to mirror the core message of Obama's candidacy."
