Her preferred presidential candidate no longer in the race, U.S. Rep. Lucy McBath has endorsed former Vice President Joe Biden for the Democratic nomination.

McBath, a Marietta Democrat in her first term, had initially backed former New York City mayor and her old boss Michael Bloomberg. Bloomberg's gun rights organization, Everytown for Gun Safety, had once employed her and spent over $4 million to help her get elected.

But Bloomberg's campaign ended a week ago after he fell far short of expectations on Super Tuesday. And race for the Democratic presidential nomination is now down to two candidates: Biden and U.S. Sen. Bernie Sanders of Vermont.

In siding with Biden, McBath has endorsed the front-runner who leads in the delegate count and is considered the more moderate candidate of the final two.

McBath represents Georgia's 6th Congressional District, a swing seat in suburban Atlanta that she won narrowly in 2018. There are five Republicans competing for the chance to face McBath this year, including the woman she unseated: former U.S. Rep. Karen Handel.

In a statement about her Biden endorsement, McBath said she believes he is the most qualified of the remaining candidates to help push her healthcare and gun control agenda forward.

“As a two time breast cancer survivor and grieving mother who lost her child to gun violence, leadership is personal to me,” McBath said in a statement. “I know firsthand the painful experience when our laws fail to protect our families. I know how important it is that health insurance is accessible and affordable. And that is why I am endorsing Vice President Biden. He has a record of bringing people together and finding common-sense solutions, and I am proud to stand with him in this race.”
