ATLANTA — If Democrats want to win statewide in Georgia, they’ll need to start now by reaching out to key constituencies and dedicating more money and resources to building up a network of grass-roots supporters. That’s the consensus emerging after widespread losses in the recent election, though a debate looms over what issues Democrats should be emphasizing and how best to convey that message to voters. “We should have been out there educating people more on all that we have accomplished, and that what we’ve done makes a difference,” said Senate Democratic Leader Steve Henson, D-Tucker.
