Abstract

While there has been a good bit of scholarly attention paid to career dynamics in—including retirements from—the U. S. House of Representatives, relatively less attention has been paid to the Senate. The few studies of career decisions in the upper chamber (e.g., Bernstein and Wolak 2002; Masthay and Overby 2017) have focused on the more or less modern Senate. In this study, we extend the time series back to the early 1900s, taking in the entire century of the popularly elected Senate. In doing so, we increase our analytical leverage to explore dynamics in the frequency, ratio (compared to electoral defeats), and direction (i.e., progressive ambition or retirement from public life) of voluntary departures from the upper chamber. We are particularly interested in the ability of the parties to retain Senate seats opened up by voluntary departures and focus our multivariate analysis on that question. Among our most noteworthy findings are 1) that the partisan differential in retirements so obvious in the House (with Republicans outpacing Democrats in voluntary departures) is absent not only in the modern Senate but over the entire history of the elected chamber, and 2) that the GOP is systemically better at retaining open seats in the upper chamber, a finding consistent with other work on party asymmetries.
