Democrat Hillary Clinton's campaign is beefing up its staffing in Georgia as polls show the race is tightening here.

The campaign told the Georgia Democratic Party late Sunday that it is sending Tracey Lewis, a Clinton deputy, to Georgia as a senior adviser to coordinate grassroots engagement activities and get out the vote efforts.

The details come from a person familiar with the conversations with Clinton’s campaign who is not authorized to speak publicly.

Georgia hasn’t turned blue since Bill Clinton’s 1992 victory in the Peach State, but Georgia Democrats hope a mix of changing demographics and Donald Trump’s divisive campaign turn it into a battleground.

An Atlanta Journal-Constitution poll released last week showed Clinton with a slight edge over Trump in the state, and days later the Clinton campaign let it be known it was sending money to Georgia to hire more field organizers. The campaign plans to make the transfer, an initial six-figure sum to "expand organizing capacity," on Monday.

Lewis was the chief operating officer for Michelle Nunn’s 2014 campaign for an open U.S. Senate seat and was also Sen. Elizabeth Warren’s deputy campaign manager in 2012. She helped organize the Democratic National Convention and was Clinton’s primary states director.

Trump’s campaign, which has a handful of staffers in Georgia, has scoffed at Clinton for investing in a state that Mitt Romney won by roughly 8 percentage points in 2012.

Brandon Phillips, the campaign’s state director, said last week Clinton's investment in the Peach State amounts to “the only jobs Hillary will be creating in Georgia.”
