Democratic Vice-Presidential nominee Joe Biden unleashed his toughest attacks on Republican Presidential nominee John McCain calling him out of touch with the middle-class.

Biden is linking McCain to the economic policies of the Bush administration, describing him as out of touch with middle-class Americans and claiming he is in the pocket of big oil and other corporations.

“John McCain doesn’t seem to understand what middle-class people are going through today,” Biden said at a campaign stop. “I don’t doubt that he cares. He just doesn’t think that we have any responsibility to help people who are hurting.

“My dad used to have an expression: Don’t tell me what you value. Show me your budget, and Ill tell you what you value. By that measure, John McCain doesn’t stand with the middle class. He stands with George Bush firmly in the corner of the wealthy and well-connected,” Biden said.

I see that Biden is returning to the theme of linking McCain to the Bush administration. Maybe the Obama campaign regrouped over the weekend.
