Sen. Bernie Sanders (I-Vt.) won Nebraska’s Democratic caucus by a comfortable margin on Saturday, taking most of the state’s 30 delegates.

There was no polling in Nebraska ahead of the caucus, but the results reflect Sanders’ electoral strengths relative to his Democratic presidential rival Hillary Clinton.

Sanders has performed well in caucus states where devoted party activists play an outsized role. That is especially true in Nebraska, where only registered Democrats were allowed to participate.

Sanders beat Clinton in the Minnesota and Colorado caucuses on March 1. He also earlier held the former Secretary of State to a narrow margin of victory in the Iowa and Nevada caucuses.

The victory in Nebraska, where the vast majority of Democratic voters are white, also reflects Sanders’ greater success with white voters than people of color.

However, he has struggled to make inroads among African American Democrats and, to a lesser extent, Latinos.

Clinton dominated among both groups on Super Tuesday.

Sanders lack of success with minority voters is a major reason why he is now significantly behind Clinton in the race for the Democratic presidential nomination.
