"They also happen to be Republicans who know how to work with Democrats and independents," Giuliani said at the Standard Club of Chicago. "Frankly, we need more of that in Washington."
When asked how important the two races were to Republicans maintaining control of the U.S. House, Giuliani expressed confidence that the GOP majority was not in jeopardy.
"I'm not going to say it's a foregone conclusion, but I'm pretty confident we're going to keep control of the House of Representatives," Giuliani said. "The question is who do we have? And I think these are two of the best for being able to practically work with both sides to get things done."
Democrats need a net gain of 25 seats to take back control of the House and the party has said Illinois is central to that effort. Democrats drew new congressional district boundaries and hope to gain four or five seats here.
Biggert, a seven-term lawmaker, is being challenged by former Democratic Rep. Bill Foster of Naperville in the west and southwest suburban 11th Congressional District. Dold, a freshman, faces Democrat Brad Schneider of Deerfield in the North Shore 10th District race.
Foster has a new ad that takes Biggert to task on Social Security and Medicare.
