Former president George H. W. Bush officially announced his support for Georgia Republican candidate David Perdue. Although Bush’s endorsement might have seemed inevitable, Perdue’s Democratic opponent, Michelle Nunn, was until recently CEO of a foundation started by the former president and has trumpeted her H.W. ties on the campaign trail

Nunn, daughter of longtime senator Sam Nunn, has cited her work as head of the Points of Light Foundation, a nonprofit founded by Bush, in a bid to win over conservative voters in the right-leaning state. (She is currently on leave from the foundation, according to the Atlanta Journal-Constitution.)

Following word of Bush’s announcement, Nunn has continued to point to her work with the organization as evidence of ”the kind of senator I will be.” She does have endorsements from a few prominent Republicans: Retired senators Richard Lugar of Indiana and John Warner of Virginia have both backed their former colleague’s daughter.

In his own statement, Bush called Perdue an “independent voice for Georgia” and emphasized the need to change the Senate’s current leadership. Polls show the race to be tight, but generally give the edge to Perdue.
