In a first of a kind debate, Democratic Presidential candidates will sound off on a variety of issues tonight... issues that YOU want to know more about. The CNN-YouTube debate is being held tonight in South Carolina, but the questions will be from folks all over the country or world for that matter. People have been submitting questions through the YouTube website. I've been watching some of the questions posted on their website and of course, some are really silly, but there are some that are very intriguing and well thought out. Not to mention, since these are videos, they are very visual, so you really understand why these questions or causes are important to the person asking them. For example, these two brothers are asking a question about health care and Alzheimer's research as they stand there feeding their mother who is in a wheelchair, suffering from many ailments, such as Alzheimer's. It really makes me glad to know that people are taking this debate seriously and are submitting some very thoughtful questions. Just check out the debate at 7 p.m. ET. tonight on CNN or YouTube.com to see some of the questions for yourself.
