## Federal
### United States Senate

Incumbent Democratic Senator Barbara Mikulski ran for re-election against Republican Eric Wargotz and many third-party and independent candidates. She previously won senate elections in 1986, 1992, 1998, and 2004 by margins of 21, 42, 41 and 31 percentage points, respectively. She won the Democratic primary with token opposition and defeated Republican Eric Wargotz 62%-38%. With her victory and service to the end of her term in January 2017, Mikulski tied Paul Sarbanes as the longest-serving senator in state history, and also becoming the longest-serving female senator in history.

### United States House

All eight of Maryland's seats in the United States House of Representatives were up for election in 2010. As of 2021, this is the last time that Republicans won more than one congressional district in Maryland.
