A painstaking recount began Wednesday in the recall election for a GOP state senator from Racine County, where witnesses and campaign officials watched as tabulators sifted through stacks of ballots and pored over poll records. State Sen. Van Wanggaard requested the recount earlier this month after an official canvass showed him trailing Democratic challenger John Lehman by 834 votes, or 1.2 percent of the nearly 72,000 ballots cast in the June 5 election. The state Senate currently has 16 Democrats and 16 Republicans, so the winner of the 21st District recall race will give his party majority control. However, the power balance could shift anew before the Legislature reconvenes in January, depending on the results of the November election. On Monday, state election officials ordered the Racine County Board of Canvass to begin the recount. By state law, the board has 13 calendar days from when the order was issued to complete the task. In this case, because that date falls on a Sunday, the board will have until the following day: July 2. Meeting that deadline could be a challenge. Two months ago the same board conducted a recount in a judges’ race that involved fewer than half the number of ballots. That effort stretched into the eighth day. County Clerk Wendy Christensen said she expected the current recount to be time-consuming but was confident the county would meet its deadline. She said the tabulators would work Saturday and take Sunday off, but that they may end up working the following weekend.
