WASHINGTON (AP) - A smiling Mitt Romney making his way to New Hampshire told reporters that he spoke with all his GOP rivals except Newt Gingrich on Tuesday night. Romney says he only got about two hours of sleep as the wait for final Iowa caucus results stretched into the early morning.
    
Romney says he and wife Ann learned from his campaign manager that he had pulled out a narrow win.
    
Aboard his campaign plane, the former Massachusetts governor wouldn't characterize his victory margin of only eight votes when asked if it would have been better to win in a landslide.
    
Romney says landslides are terrific, but he didn't see that in last night's figures.
