WASHINGTON--Former New York Mayor Rudy Giuliani headlines a fund-raiser for Rep. Mark Kirk's Illinois Senate campaign Sept. 13 in Chicago.

Giuliani, who ran for president in the 2008 GOP primaries, has stumped for Kirk before, appearing with him in his north suburban 10th congressional district in 2008 and for his 2010 Senate primary contest.

The Kirk campaign thinks Giuliani will help draw in female suburban voters who will see Kirk in the Giuliani mold as a fiscal conservative, social moderate and national security hawk.
