John McCain is calling for a presidential election season that's more like a respectful argument among friends than a bitter clash of enemies.
The Republican nominee-to-be says there are key differences to be settled in the fall on issues such as energy, the housing crisis and terrorism. And he says it is "our civic and moral obligation" to "fight among ourselves for the things we believe in."
But, he says it's important to remember that "we are not enemies."
McCain also says if elected, he would attempt to govern in the same spirit, saying his record of reaching across the aisle is unmatched by either Hillary Rodham Clinton or Barack Obama.
