AJC PolitiFact Georgia went back in history last week on its search for the truth. Way back. Like a century ago -- the dawn of our nation's dependence on fossil fuel. That's when wooden pipelines were used to transport natural gas. We found out whether they're still in use today. And two decades ago, when Georgians debated whether to institute the lottery that now funds the popular HOPE Scholarship for college-bound high schoolers. Did former Gov. Roy Barnes, who's trying to reclaim his seat, oppose the scholarship? The Truth-O-Meter's other jaunts into the past had to do with more recent history. Think five years ago, when the state argued over whether to toughen its voter ID laws. Or the turn of the millennium, when Barnes, a Democrat, was governor. Republicans claimed he was weak on education and jobs back then. It's also when a DeKalb County school board member said she started handing over to the county what totaled $30,000 in unused travel money. Did she? This is how we ruled.
