WASHINGTON (CNN) -- North Carolina GOP Sen. Elizabeth Dole, the chairwoman of the National Republican Senatorial Committee, brushed aside suggestions the Iraq war would cause widespread GOP loses and said that the Democrat's plan for the war-torn country would increase the threat of terror to the United States.

"For a person to think that voting for a Democrat for the Senate is going to fix the situation in Iraq makes no sense," Dole told CNN's Soledad O'Brien on 'American Morning.' "That's just not the case. Let me point out here, too, that for us to leave -- and it seems that Democrats are saying they're satisfied or content with losing, if we were to withdrawal from Iraq at this point, there's no question that this would leave a void there, a breeding ground for attacking the United States again."

Dole also pointed to historical trends unfavorable to a president's party in midterm elections as a reason some GOP candidates from Republican friendly states are locked in tight races.

"A midterm election is always tougher," Dole said. "When a president has been re-elected, there's that six-year itch, and history shows that it becomes even tougher. Our candidates have known that all along, since the first day that I arrived at the senatorial committee, we realized what this cycle would be like."
