Harvard Professor Danielle Allen announced Tuesday that she is dropping out of the Massachusetts governor's race, but she's not giving up on her efforts to move the state forward on voting rights, she told Jim Braude on Greater Boston.

Allen said suspending her campaign came down to "pure math."

"The caucuses started and we have a very impressive candidate in the form of the attorney general [Maura Healey] and she did her work and we did our math and there was no path. And when that happens, you make the call," said Allen.

Allen said she hopes to continue addressing barriers in voting rights such as getting your name on the ballot to run for office.

"We aren't getting everything that we need out of Washington, so all the more important for us to stick by our principles and say 'Yeah, no, we can do better.' We don't need these unnecessary barriers to voice and choice," she said.

Although Allen's run for governor came to an end, she said, "it has been the honor of my life, the joy of my life, and honestly it's just the beginning because I had too much fun."
