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.
