Joe Biden will deliver a high-profile address intended as the first attack in a sustained anti-McCain offensive in a speech called "Bush 44" he'll deliver Monday in the key battleground state of Michigan.

While the lines of attack have long been drawn, Biden will assert — as the title indicates — that a McCain presidency would amount to a third Bush term and will focus, in a detailed, comprehensive and aggressive way, on John McCain's domestic policies and harsh campaign tactics, a campaign aide told Politico.

Minnesota has become a battleground in a presidential campaign that has dramatically tightened nationwide.

A new Star Tribune Minnesota Poll shows that the race is now a dead heat between Barack Obama and John McCain, each supported by 45 percent of likely voters in the state.

On This Week this morning, Sen. Claire McCaskill, D-Mo., a surrogate for the campaign of Sen. Barack Obama, D-Ill., raised the age and health of Sen. John McCain, R-Ariz., when discussing the qualifications, or lack thereof, of Alaska Gov. Sarah Palin.

McCaskill said she stood by her remarks that she's "uncomfortable with anyone, regardless of gender, that is going to be vice president to one of the oldest presidents we've ever had that has never met a world leader."

When Stephanopoulos asked her it was fair to raise McCain's age, McCaskill doubled-down and mentioned his past skin cancer, saying, "I think what we're talking about is a reality. Other people talk about his melanoma. We're talking about a reality here that we have to face. This is someone who's going to be one heartbeat away from the presidency. All of us know it. I just think that it's the facts, George, and that's something that we need to start focusing on, are the facts, instead of distortions and lies."

But, Obama cannot change who he is despite what his supporters perceive. Jeremiah Wright and Bittergate are aspects of his character voters will not ignore. Look at this comment/quote:
“I just do not trust the American people,” said Eleanor Shavell, 58, a computer programmer, who, along with several others, joked she would move to Canada if Mr Obama loses. “I cannot believe that 80 per cent of this country thinks we’re headed in the wrong direction yet 50 per cent are supporting McCain and Palin. I guess it’s like at school, there’s always got to be a bottom 50 per cent.”

The Rasmussen Reports daily Presidential Tracking Poll for Sunday shows John McCain reaching the 50% level of support for the first time since Barack Obama wrapped up the Democratic Presidential Nomination. McCain retains a three-point advantage for the third straight day, 50% to 47% (see recent daily results).
