MADISON, Wis. (AP) -

A La Crosse Republican looking to unseat the state Senate's Democratic leader has until Wednesday to ask for a recount.

Dan Kapanke is trying to defeat Senate Minority Leader Jennifer Shilling. Unofficial Election Day results showed Shilling with a 58-vote lead. The official canvass the four counties in their southwestern Wisconsin Senate district turned in to state election officials on Friday showed Shilling ahead by 56 votes.

Under Wisconsin law, candidates have three days to request a recount once the official canvass has been filed. That gives Kapanke until Wednesday to make a decision. The recount would be free since the margin between the candidates is less than .25 percent of the total votes cast.

Senate Democrats plan to meet Tuesday to select their leaders for the upcoming session.
