WASHINGTON—With the election just a little more than a week away, Hillary Clinton holds a commanding 26-point lead over Bernie Sanders in the Democratic presidential primary in Tennessee, a new poll says.

Clinton has the support of 58 percent of Tennessee voters, while Sanders gets 32 percent, according to the survey by the group Public Policy Polling.

Clinton, a former secretary of state and U.S. senator, has held a steady lead in the Volunteer State in the weeks leading up to the March 1 primary.

A poll conducted in January by Middle Tennessee State University showed her with a 32-point lead over Sanders, but suggested nearly 26 percent of Democratic voters remained undecided.

The most recent poll, released Wednesday, showed Clinton leading not only in Tennessee but in 10 of the 12 states that will hold primaries between March 1-8.

Sanders, a U.S. senator from Vermont, has an overwhelming lead in his home state and also leads in Massachusetts.

While Clinton easily won Tennessee's Democratic primary in 2008, she lost to Barack Obama in Memphis and Nashville.

Clinton is targeting African-American voters as part of her first television ad buy in Tennessee. The campaign said it is spending at least $100,000 on the spots running the Memphis and Nashville markets.

The first ad running Memphis addresses what Clinton calls the "fundamentally broken" criminal justice system that disproportionately targets African-Americans.

The Clinton campaign is opening a grass-roots organizing office at 3177 Poplar in Memphis on Thursday. A number of elected officials and community leaders were scheduled to attend, including U.S. Rep. Steve Cohen and state Rep. Raumesh Akbari, Memphis Democrats who are backing Clinton.

The Sanders campaign formally opened its Memphis office last Saturday. It's at 2869 Poplar.
