Why do five of the fifty state legislatures (New Hampshire, New Jersey, North Carolina, Vermont, and Washington) make comprehensive floor roll call votes on bills available online by legislator, while most states only provide online access to roll call votes by bill? That was a question that we received from a researcher at the Kennedy School of Government who is doing a study of legislative information systems in Congress, the fifty states, and the 25 largest U.S. cities. He adds that neither Congress nor the 25 city councils provide roll call voting information by legislator, making the five state legislatures that do even more unusual.
The researcher had some hypotheses in mind (district population and legislative salaries) that might explain why some states provide this information and others don't, but he wanted to know if we had other ideas. Going on instinct alone and unburdened by any research or data, here was my response:
I'm not sure I have an answer for you. A standard first question that political scientists would ask about this would be to check it against legislative professionalization. Using the standard three levels of professionalization, among the five cases that you mention, two (NH and VT) are classic part-time citizen legislatures, one (NJ) is a professionalized ("full-time") legislature and two (NC and WA) are hybrid or in-between. Nothing apparent there. The professionalization measure is highly correlated with state population, and as you point out yourself, the NJ case belies a district population explanation. The professionalization measure also includes compensation of legislators, which you suggest you want to test as an independent variable. I would suggest using professionalization instead of compensation by itself, but I don't think either one will yield a useful result.
There's also no apparent regional or socio-economic factor among the five states.
The other thing that I would suggest is that roll call voting by legislator is highly political information, subject to misinterpretation and campaign demagoguery. That's the main reason why most legislatures don't make the information easy to obtain. It's inherently anti-incumbent information, and since incumbents run the system, they don't make a practice of releasing it. With the exception of NJ, most of the legislatures that provide this information are somewhat less partisan than most, although there are plenty of others that are equally low in partisanship that don't make the info available.
With only five cases to go on, I think that idiosyncratic explanations will prevail. For different reasons in each of these states, there is probably a tradition, a provision in the rules or constitution. or a whim of a leader that made roll call votes by legislator available online. I know that's not a very satisfying explanation to a social scientist, but sometimes randomness does prevail!
Anybody have any better explanations? If you're in one of the states that provide the roll call information by legislator, how was the decision made to make it available? If you're in one that does not, have you considered this option?
