With Election Day only months away U.S. Senator Dick Durbin is finding himself defending some of his Democratic colleagues.

The senior senator for Illinois was in Chicago on Thursday to announce a new environment conservation project. He also answered questions about the competitive presidential race.

Presumptive Republican presidential nominee Mitt Romney alleged, also on Thursday, that President Barack Obama cut Medicare funding to pay for the Affordable Care Act. Durbin said some Republicans are upset with Obama’s healthcare overhaul because it fought against insurance companies.

“You really have 17 angry, old white men who are putting money into these Super PACs like Sheldon Adelson and they are just running streams of negative campaigning,” he said.

Adelson is one of the many wealthy supporters funneling money into Romney’s campaign.

Durbin said that instead of paying for negative ads Republican backers should focus on the issues in a more constructive way. He was also asked whether Vice-President Joe Biden should leave the ticket, in light of his recent gaffes.

Durbin said that’s an overreaction and that Biden is a great partner to the President.
