The answer seems to be yes. According to a recent study:
Just before U.S. Presidential elections, judges on the U.S. Courts of Appeals double the rate at which they dissent and vote along partisan lines. Increases are accentuated for judges with less experience and in ideologically polarized environments. During periods of national reconciliation — wartime, for example — judges suppress dissents, again, especially by judges with less experience and in ideologically polarized environments. We show the dissent rate increases gradually from 6% to nearly 12% in the quarter before an election and returns immediately to 6% after the election.
