EMILY's List is endorsing Democratic power broker Debbie Dingell in the race for her husband's seat.
"Debbie Dingell is a strong Democratic leader with over 30 years of experience as a business executive, and she is deeply committed to helping Michigan women and families have a fair shot," said EMILY's List President Stephanie Schriock in a release.
The group, which backs Democratic women who support abortion rights, has long been a Dingell ally. When she mulled a Senate run last year against Rep. Gary Peters (D-Mich.), EMILY's List signaled it would back her in the race.
The Michigan seat has been held by a Dingell since John Dingell Sr. took it in 1933. His son, the current representative, has served in it for 60 years.
