MADISON, WI (WTAQ) - A new poll shows that Governor Scott Walker continues to lead his Democratic challengers in his June 5th recall election.

But Walker’s lead over Tom Barrett is within the poll’s margin of error, which makes it a statistical dead heat.

The Public Policy Polling firm interviewed over 1,100 likely voters last Friday through Sunday. And in head-to-head matchups, the Republican Walker led Barrett 50-45 percent – the only one within the poll’s 2.9 percent error margin.

Walker led Kathleen Falk 50-43 percent, Doug La Follette 51-40, and Kathleen Vinehout 50-38.

Over 800 of those polled were planning to vote in the Democratic primary 3 weeks from Tuesday.

Barrett was the leader with 38 percent to 24 for Falk, 9 percent for La Follette, and 6 percent for Vinehout. 22 percent were still undecided.

The Public Policy poll also showed that Republican Lieutenant Governor Rebecca Kleefisch led Democrat Mahlon Mitchell, the head of the state firefighters’ union, 46-40 percent.
