WASHINGTON (AP) - Democrat Heidi Heitkamp's campaign says she raised $500,000 for her U.S. Senate bid in the final quarter of 2011.
    
Heitkamp's campaign released her fundraising numbers to The Associated Press on Friday. The former North Dakota attorney general and one-time gubernatorial candidate is running to replace
Sen. Kent Conrad, also a Democrat, who is retiring at the end of his term.
    
Heitkamp's fundraising reflects the final quarter of 2011, when she announced her bid. She is running against GOP Rep. Rick Berg.
    
Berg hasn't released his fundraising totals for the most recent quarter yet. But the congressman reported having raised about $1 million as of September 2011.
