Democrats don’t care about this. This won’t affect their vote, nor do the 18 year olds care. This is distant history, happened long before they were even born. Do they care? No. I agree that Ayers should be a disqualification for Obama, but we’re not dealing with any critical thinking on the left.
The fight is over the middle 20% who WILL be influenced by BHO's associations, including Ayers, Wright, et al.
