"When people get to know my track record and contrast it with John McCain's, when they know that I'm giving a middle-class tax cut to working families, and he's giving a tax cut, a quarter of which goes to people making more than $2.8 million, when people see that I'm offering universal health care, and John McCain is not, those are going to be decisive issues during a year when families, like those here in Flint, are really feeling left behind," Obama said.
The presumptive Democratic nominee campaigned in Flint today, and will be joined for the first time by Gore at a campaign event in Detroit tonight.
"A few hours from now I will step on stage in Detroit, Michigan to announce my support for Senator Barack Obama," Mr. Gore said in an e-mail sent to his supporters Monday. "From now through Election Day, I intend to do whatever I can to make sure he is elected President of the United States."
Asked whether he is bothered by the gay marriage ceremonies performed across California today, Obama, who personally opposes same-sex marriage, said "No."
The presumptive Democratic nominee said he stands by his pledge to repeal the Defense of Marriage Act — the 1996 law passed by Congress and signed by President Bill Clinton that stipulates states don't have to recognize other states' marriages if not between a man and a woman.
"I believe that marriage is between a man and a woman, but I also think that same-sex partners should be able to visit each other in hospitals, they should be able to transfer property, they should be able to get the same federal rights and benefits that are conferred onto married couples." Obama told ABC News.
Obama said he strongly supports civil unions.
"I still think that these are decisions that need to be made at a state and local level," he said. "As president, my job is to make sure that the federal government is not discriminating and that we maintain the federal government's historic role in not meddling with what states are doing when it comes to marriage law. That's what I'll do as president."
Obama blasted the Bush administration for its handling of Guantanamo and said they have given "a huge boost to terrorist recruitment in countries that say, 'Look, this is how the United States treats Muslims.'"
The Illinois senator, a former constitutional law professor, said while he hasn't opposed the national security surveillance program in theory, the Bush administration has "been willing to skirt basic protections that are in our Constitution, that our founders put in place."
"It is my firm belief that we can track terrorists, we can crack down on threats against the United States, but we can do so within the constraints of our Constitution. And there has been no evidence on their part that we can't."
Pointing to Guantanamo Bay, Obama said the fact that so few of the people being held by the U.S. have had a trial has destroyed U.S. credibility around the world when it comes to rule of law.
"We could have done the exact same thing, but done it in a way that was consistent with our laws," he said, pointing to the incarceration of people involved with the first bombing of the World Trade Center.
