Republican Wisconsin Gov. Scott Walker raised $48 million in his bid to stave off challenger Tom Barrett in today's recall election. Meanwhile, Barrett pulled in $19 million Barrett, according to the non-partisan Wisconsin Democracy Project. About $20 million to $30 million is from out-of-state donors, including a number of Walker supporters in Illinois. The Sun-Times reports:

Conservative Lake Forest businessman Richard Uihlein has given $105,000 to Walker. Barrington industrialist Jack Roeser is in for $2,500.

Chicagoan Keith Bronstein of Tradelink gave $25,000 and Gretchen Schuette, a member of the Wausau Homes family living in Sugar Grove, Ill., gave $50,000.

Contributions listed for Barrett from Illinois residents are less substantial: the highest noted by the Sun-Times was for $10,000.

Walker enjoys a narrow lead in two polls released from the weekend.
