Raoul reported receiving a $1 million campaign check late Friday night from House Speaker Michael Madigan, as part of a final flurry of campaign cash to help push the Hyde Park Democrat across the electoral finish line with a victory in his first statewide race. The African-American state senator also is seeking to benefit from a late radio ad cut by the predecessor of his Springfield seat: former President Barack Obama, who also will appear at a Sunday rally for the Democratic ticket at the University of Illinois at Chicago.
