Top Dems want Obama's positions spelled out

The San Francisco Chronicle reports:

As Sen. Barack Obama prepares to accept the Democratic presidential nomination next week, party leaders in battleground states say the fight against Sen. John McCain looks tougher than they imagined, with Obama vulnerable on multiple fronts despite weeks of cross-country and overseas campaigning.


These Democrats - 15 governors, members of Congress and state party leaders - say Obama has yet to convert his popularity among many Americans into solutions to crucial electoral challenges: showing ownership of an issue, like economic stewardship or national security; winning over supporters of Sen. Hillary Rodham Clinton; and minimizing his race and experience level as concerns for voters.
