DES MOINES, Iowa (Reuters) – Mike Huckabee has surged into a virtual tie with front-runner Rudy Giuliani in the national 2008 Republican presidential race two weeks before the first contest, according to a Reuters/Zogby poll released on Wednesday.
Huckabee, a former governor of Arkansas whose campaign has caught fire in recent weeks, wiped out an 18-point deficit in one month to pull within one point of Giuliani, 23 percent to 22 percent.
Among Democrats, Hillary Clinton’s national advantage over second-place rival Barack Obama shrunk slightly to eight percentage points as the races for the White House tightened in both parties. Clinton had an 11-point edge last month.
