(CNN) - The campaigns of frontrunners John McCain and Barack Obama continued to battle Wednesday morning, as staffers followed a night of tough speeches with morning disputes over campaign finance and foreign policy.
Both men won the Wisconsin primary Tuesday night, and used their victory speeches to take aim at each other. Obama said the Republican senator represented the past; McCain said the Illinois Democrat’s views on foreign policy were "no more than a holiday from history.”
Wednesday morning, the McCain called Obama "naive" for saying he'd be willing to use military action against "our ally in Pakistan."
Obama said earlier in the campaign that he would consider using military force in Pakistan against terrorists without the permission of the Pakistani government.
One of the Obama campaign’s senior foreign policy advisers responded by once again linking McCain with George Bush – a frequently-used recent campaign trail theme.
On a conference call with reporters, former Clinton administration official Susan Rice said that McCain's "approach to foreign policy is very much a continuation of the flawed Bush policy - he really is in many respects just four more years of George Bush."
Rice added that "it's a strange contrast: he says that somehow it's naive for a presidential candidate to outline how he would deal with that crucial national security challenge, but it's appropriate for him to joke about starting another war."
Before the New Hampshire primary, McCain responded to a foreign policy question with a refrain of "bomb, bomb, bomb, bomb Iran," sung to the tune of the Beach Boys hit “Barbara Ann.”
