RALEIGH, N.C. (AP) -- North Carolina Democrat Kay Hagan has served four years in the U.S. Senate, and soon her 2014 re-election bid will begin.

In an Associated Press interview, the former Greensboro state senator called herself a middle-of-the-road, independent thinker who is working to improve North Carolina's economy and break the gridlock in Washington. She's also gone out of her way to be visible and engaged in North Carolina, coming home every weekend.

Engagement back home won't be enough alone to win another six-year term. Republicans invigorated by recent wins are weighing whether to challenge her.

Her re-election may ride on how the public views President Obama in late 2014. Hagan says the race will be less about party and more about the person running -- herself.
