Sonia Sotomayor isn't much of a voter. She skipped multiple New York elections in the past decade, including three for state supreme court, reports NY1. The 2nd Circuit appeals judge failed to vote for governor in 2002 and 2006, and for court positions in 1995, 1999, and 2007. Sotomayor is not registered with any party and thus cannot vote in party primaries. She did vote in the 2008 general election, the one won by the guy who wants to put her on the Supreme Court.
“They tend to throw the kitchen sink at whoever has been nominated, Republican or Democratic so I'm sure it will come up” in the confirmation hearings, said Gene Russianoff of NYPIRG. “People look to state officials, federal officials as role models that send a message to be involved in government, to be involved in this society. So it's unfortunate that she missed a bunch of elections."
