MADISON, Wis. -

Republican Dan Kapanke is planning to seek a recount in his bid to unseat state Senate Minority Leader Jennifer Shilling.

Kapanke's campaign said in a statement Tuesday that Kapanke had decided to request a recount because the results were so close. Returns show Shilling with a 56-vote lead. The campaign plans to formally file the request Wednesday.

Wisconsin Elections Commission spokesman Reid Magney says the four counties in the 32nd Senate District -- Crawford, La Crosse, Monroe and Vernon -- would then have to start counting no later than Monday. He expects the recount could from three to six days.

Despite the uncertainty, Shilling planned to run for leadership position again when Senate Democrats choose officers Tuesday for the upcoming session.
