Garcia, the executive director at the nonprofit Colorado Statewide Parent Coalition, tweeted on Tuesday that she’s running against Gardner to focus on “economic equity for all,” arguing for the need for a “new voice” in the Senate.

“We are at a crossroads in our history where we can no longer accept the status quo and must take action to fix our broken government systems,” Garcia, a self-described progressive, said in a statement, according to the Colorado Springs Independent.

“I’m running because we need innovative leaders who will work on behalf of the interests of every Coloradan, not for political self-interest.”

A first-time candidate, Garcia currently works for a nonprofit organization that provides training for parents to be involved in their children’s education. She’s also previously worked with communities in Nepal and Nicaragua as the executive director of Namlo International.

Gardner, chairman of the Senate GOP’s campaign arm in the 2018 cycle, is one of the Democrats’ top targets in 2020, though he is a formidable campaigner.

Democrats will be battling for the Senate majority in 2020 after losing a few seats in the midterms. If Republicans win Mississippi’s Senate runoff on Tuesday night, they’ll have a 53-47 seat majority.

With Mississippi still up in the air, Republicans will be defending at least 21 seats, while Democrats will be protecting 12 seats.
