What does a pair of Senate candidates do when their state is booming amid a sluggish national economy?
They focus on personal style. That's the case in North Dakota, where Democrat Heidi Heitkamp and Republican Rep. Rick Berg are waging a surprisingly tight race for an open Senate seat.
Heitkamp is emphasizing her record as a former state attorney general. Berg is highlighting his support for conservative issues and trying to tie Heitkamp to national Democrats.
The race is one of three for the Senate that have shifted from nearly certain Republican wins to toss ups. The GOP needs a net gain of four seats to take control of the Senate, a goal that seemed within reach not long ago but has turned uncertain two months before Election Day.
