"It appears that John McCain is very much a creature of Washington and one of the things that we've said from the outset of this campaign is that if we're gonna change policies, if we're gonna deliver on universal health care or have an energy policy that over the long term can bring down gas prices that we were gonna have to change how Washington works," Obama told reporters Sunday at an ice cream shop in Milwaukie, Ore. "We can't have special interests dictating what's happening there and that's why I said at the beginning I wouldn't take PAC money and I wouldn't take money from federal lobbyists. And it does appear that over the last several weeks John McCain keeps on having problems with his top advisers being lobbyists, in some cases for foreign governments or other big interests that are doing business in Washington that I don't think represents the kind of change that the American people are looking for."

"It's the biggest anti-Washington streak in the American electorate in decades, and McCain's problem is that his campaign is full of Washington-lobbyist types," said Chris Kofinis, a former John Edwards aide. "You can't be the guy who is striving for reform when the people who run the campaign are fighting against reform."

Democrats have hammered McCain on that very issue for months, noting that campaign manager Rick Davis and senior adviser Charlie Black have spent decades lobbying in Washington. Both have left their companies.
