In an interview with CBS News, Mitt Romney said he wouldn't engage in "character assassination" -- even if that's what some conservatives want. 

"This is a campaign, not about character assassination, even though that's what I think has come from the Obama camp by and large," the GOP presidential nominee told Jan Crawford. 

"Some people say, 'Just be who you are!' Others say, 'Get tougher! Attack!'" Romney said, when asked about conservative pundits who want him to be aggressive. "I'm going to be who I am and describe why I think I'm the person who's going to become the next president of the United States, and how my policies will make life better for American families." 

Romney has gotten pushback from supporters on the campaign trail when he says that President Obama "cares about America."
