MILWAUKEE (AP) — One state senator leads another by only 214 votes in the Republican primary for Wisconsin’s lone open congressional seat, a margin that would allow a free recount. The Associated Press called the race for Glenn Grothman on Tuesday night but uncalled it Wednesday after more votes came in for Joe Leibham and the margin shrank. Grothman was leading Leibham by just three-tenths of a percentage point Wednesday morning. Some absentee ballots could be counted if they were postmarked in time. Wisconsin law lets any candidate request a recount. But, candidates pay based on the margin. In the congressional race, the recount would be free if the margin is one-half of a percentage point or less.
