WASHINGTON (CBS) -- Mitt Romney is accusing President Obama of waging a campaign based on division and hatred. The Republican White House hopeful made the comments on "CBS This Morning."
President Obama's campaign called Romney unhinged, but the President did not respond directly as he wrapped up his bus tour through a key battleground state.
First Lady Michelle Obama joined the President on the third and final day of his bus tour through Iowa.
President Obama told supporters in the battleground state he'll protect the middle class. He says, "Four years ago I promised to cut middle class taxes, and Dubuque, that's exactly what I have done."
The president said his healthcare reforms have strengthened Medicare and argued Mitt Romney and his VP pick Paul Ryan want to turn it into a voucher program. President Obama says, "Their plan makes seniors pay more, so they can give another tax break to millionaires and billionaires."
Governor Romney headed south to raise campaign cash on Wednesday but launched his day with a sharp critique of the president's campaign. He says, "The president's campaign is all about division, attack, and hatred."
The Republican presidential candidate is taking issue with Obama campaign ads and remarks vice president Joe Biden made to supporters in Virginia Tuesday.
Talking about GOP plans for Wall Street de-regulation, the Vice President told a predominantly African American audience, they would end up back in chains under a Romney presidency. Romney says, "These personal attacks I think are demeaning to the office of the White House and the comments by the vice president yesterday just diminish the White House that much more."
The Obama campaign says the Vice President used language similar to Republicans in Congress.
While Romney infers that Biden's comments were racially insensitive, the executive director of the Virginia State NAACP said he had no comment about the vice president's remarks.
