Dash came under attack on Twitter shortly after publicly supporting Romney on Oct. 7. Most of the negative responses against the 46-year-old actress had to do with her race and gender.
"The fury, I really don't understand the fury," she told Morgan Tuesday night. "I don't understand it. I don't get it…I was shocked, saddened. Not angry. Saddened and really shocked. But you know what, you can't expect everyone to agree with you."
Dash, who admitted she voted for Barack Obama in 2008, told Morgan she believed in Romney.
"I believe him…I watched him, the Governor and his wife, on 'Meet The Press.'…They spoke to me, they seemed authentic and genuine."
One negative tweet directed at Dash read, "You're an unemployed black woman endorsing @MittRomney. You're voting against yourself thrice. You poor beautiful idiot," one user tweeted.
After the negative backlash, Dash stood by her comment, tweeting, "My humble opinion… EVERYONE is entitled to one."
Women's rights activists Sandra Fluke, who is often a target of many conservative pundits, tweeted her support for Dash.
"So disappointed to see people attacking @REALStaceyDash for voicing her opinion. Disagree politically, but #racist attacks are unacceptable."
