Lt. Gov. Walter Dalton opened a double-digit lead against rival Bob Etheridge in the Democratic primary for governor, according to the latest Public Policy Polling survey released Monday.
Dalton's 36 percent to Etheridge's 26 percent represents a huge surge in April. At the start of the month, Etheridge held a 10-point lead with many voters undecided. His advantage began to evaporate by mid-month as Dalton spent about $400,000 on a TV advertising campaign and appeared to win many of those uncommitted Democrats.
A week ago, polls showed Dalton and Etheridge in a dead heat (26 percent to 25 percent, respectively).
