The poll also found that in the race to replace Topinka in the treasurer’s office, Chicago banker Alexi Giannoulias, a Democrat, has the support of 40 percent of voters compared to 23 percent for Republican state Sen. Christine Radogno of Lemont. Green Party candidate Dan Rodriguez Schlorff got 5 percent.
But nearly 30 percent of voters were undecided in the treasurer contest and large numbers had never heard of either major party candidate, despite a series of stories about questionable loans given by the Giannoulias family’s Broadway Bank, the survey showed.
