Rather than going to the candidates websites I would suggest going to the Library of Congress or other neutral website and research what the candidates have done. Anything on their respective sites would, while being credible, be cherrypicked, edited and self-serving. Compare and contrast bills authored, bills co-authored, bills sponsored, bills signed on to and most importantly, what bills they have been involved in that actually passed. I read an interesting post on Kos from a person who actually did this research titled "I refuse to buy into the Obama Hype (now a supporter)" from Grassroots Mom.

The basic point is that Seantor Obama has had as much, if not more, substantive legislation authored and passed. It also points out that co-sponsors include those from the other party that would surprise you (Tom Coburn for example). This lends credence to the argument that he is capable of building coalitions to get things done.
I also find it interesting that the charge of lacking solutions is coming from a candidate who signed on to legislation that presented important solutions. I understand that Senator Clinton has accomplished some in her own right. One also has to take into consideration the relative time each has had to do the things they have done.
