This question can not be answered with a "ignorant" or "informed". I think there are really 3 categories, with the people in the middle forming the largest group.
There is a large group of Americans that do not pay attention to politics and are not educated enough to form coherent political views...(as evidenced by the Stern interview, Wow) Hopefully, the majority of these people will stay home on election day.
On the other end, there is a large group of people that are "plugged in" and are knowledgeable about the candidates and their policies.
In the middle, you have millions of americans that just read or listen to the headlines, forming their political views (if you can call them that, maybe inclinations would be better) based on a conversation that they had with someone at the watercooler. Busy with their everyday lives, they don't take extra time to educate themselves about the different candidates and form their own opinions. Can you blame some of these people? There is so much conflicting information about the two candidates that it is tough to figure out what is the real story.
I side with Ignorant Voters on this debate because when it comes down to it... Those americans in the middle can not be considered "Informed"
I would think that taking Personal Responsibility would be an important factor in this debate. Nobody is saying that you should not help your neighbor in need, but there is a difference between helping someone that needs it and providing handouts to those that have learned that they don't have to work to better their situation.
