EMILY’s List, an organization that backs female Democratic candidates who support abortion rights, has endorsed West Virginia Secretary of State Natalie Tennant’s bid for Senate.

“I wanted to personally let you know that today we’re endorsing Natalie Tennant for the U.S. Senate race in West Virginia,” EMILY’s List President Stephanie Schriock wrote to the group’s supporter email list.

“And if Democrats are going to keep hold of the U.S. Senate, this is a race that we have to win.”

Tennant will likely face off against Republican Rep. Shelley Moore Capito in the general election. This race will choose a successor to retiring Rep. Jay Rockefeller, D-W.Va.

The race is currently rated Lean Republican by Rothenberg Political Report/Roll Call.
