Democratic Senate candidate Michelle Nunn announced Tuesday that she has brought in $1.7 million in campaign cash since the end of July -- a formidable fundraising haul for the first-time candidate seeking the Georgia seat being vacated by Republican Sen. Saxby Chambliss.

Nunn's campaign said the money came from more than 6,700 donors, and touted more than 3,000 volunteers for the campaign so far.

Although she has not sought elected office before, Nunn's acumen for raising money is not altogether surprising: She has at her fingertips a network of donors established by her father, former Sen. Sam Nunn, D-Ga., in addition to those connections she has made as CEO of Points of Light, a major nonprofit.

Nunn also has the advantage of sailing unopposed to the Democratic nomination. Seven Republicans are currently vying for their party's nomination and, by extension, fundraising dollars.
