David Hoffman Attacks Alexi Giannoulias For Rezko Ties (VIDEO)

With just over a week before Election Day, David Hoffman has launched a new attack ad, going after the front-runner in the Democratic race for U.S. Senate .

The ad comes as new polling shows Alexi Giannoulias with a double-digit lead over rivals Hoffman and Cheryle Jackson. Hoffman did, however, show signs of life in the poll, gaining by far the biggest slice of undecided voters since the last poll in early December.

In the 30-second spot, Hoffman plays up Giannoulias's ties to Tony Rezko, the fundraiser who was convicted for fraud and money-laundering felonies during his corrupted affiliation with the Blagojevich administration. The ad asserts that Broadway Bank, owned by the Giannoulias family, lent over $1 million to Rezko.

Hoffman has been campaigning as a reform-minded outsider, and has garnered a number of endorsements from major newspapers in recent weeks for precisely that reason.
