Little more than a week ago, Georgia appeared to be slipping out of Democrats’ reach. President Joe Biden’s campaign was pledging to concentrate more on holding the “blue wall” states in the Midwest and suggesting they might be willing to forsake “Sun Belt” battlegrounds. But now that Biden has bowed out of the race and Vice President Kamala Harris is the likely nominee, the Democrats say they have new hope for Georgia. They’re betting a fresh burst of energy and a surge in fundraising has helped make Georgia a toss-up again. Harris plans a show of political force Tuesday in Atlanta, with a large rally like those held by Republican ex-President Donald Trump.
