States with term limits have higher proportions of former state legislators serving in Congress than states without term limits. The national average of former legislators in Congress is 50.5 percent, ranging from 100 percent (of three seats in the U.S. House and Senate) in Montana and Wyoming to zero percent (of five seats) in New Mexico. But among term-limited states the average is 60.7 percent compared to 46.1 percent in non-term-limited states.
I arrived at these numbers by a somewhat circuitous route. Several weeks ago, the Sacramento Bee had an interesting story, "Political merry-go-round diminishes Democrats' clout in Legislature." The premise of the story was that California Democrats are very close to having the two-thirds majorities necessary to approve budgets in both chambers of their Legislature, but they are continually stymied by having vacancies in the Legislature created by legislators moving to other offices. For example, two California members of Congress have been appointed to positions in the Obama Administration. It is likely that current state legislators will run for those seats, causing vacancies in the Legislature. A state senator moving on to another office often creates a vacancy in the Assembly because Assembly members move to the Senate.
What the story does not say is that, from a comparative perspective, California has a unique set of circumstances that exacerbate the problem of musical chairs in the Legislature. First, it is the only state that has more members of Congress (55 including U.S. senators) than it does state senators (40). This means that California state senators who want to move to Congress are especially well-positioned to do so, as they are likely to have already run and won in districts larger than the congressional ones. Second, along with Arkansas and Michigan, California has the most restrictive of all term limits: six years in the Assembly and eight in the Senate and a lifetime ban on any further legislative service. California legislators who want to continue a career in politics have especially strong incentives to run for other offices.
This got me to wondering about the career path from state legislatures to Congress, how the number of former state legislators serving in Congress varies from state to state and what might explain the variation. To get at this, I turned NCSL's list of former legislators serving in Congress into numbers by state.
