From the International Herald Tribune:

A Democrat has won the congressional seat of former House of Representatives leader Dennis Hastert in a closely watched special election in the longtime Republican district.

Bill Foster has won 52 percent of the vote compared to 48 percent for Republican Jim Oberweis with 556 of 568 precincts reporting.

Foster’s special election win Saturday means he will fill the remainder of Hastert’s term until it ends next January.
