I do not agree with you about that at all. In fact, Kerry's Senate Office web site displays in great detail the history of each and every bill that Kerry has sponsored over the last 10 years. Sponsorship of bills which eventually become law is indeed a measure of a Senator's effectiveness. That being the case, raw data about numbers and eventual results do matter.

 Now as to the point you make which is that there are also other measures of effectiveness. That indeed can be true, but I can find no data trail on Kerry's Sentate Office web site which supplies me with information about any bills which Kerry, either as an significant amender or as a co-sponsor, helped become law. I would like to see some information about bills which Kerry co-sponsored which became law. I am sure there are some, I just haven't located any data which corroorates that, have you?  Also, the raw statistics about what did and did not become law is a concise window into this area. In addition to the table showing numerical results, what else do you suggest we add to give a more detailed view into Kerry's work product in the Senate?
