Born in Los Angeles, California, Watson was raised Catholic as the daughter of William Allen Louis Watson and Dorothy Elizabeth O’Neal Watson. According to a DNA analysis, some of her ancestors were from the Central African Republic. She was educated at Dorsey High School, Los Angeles City College and the University of California, Los Angeles, where she earned her BA in Education (1956) and became a member of Alpha Kappa Alpha.

She earned an MS from California State University, Los Angeles in School Psychology (1967) and a PhD in Educational Administration from Claremont Graduate University in 1987.

Watson taught elementary school and was a school psychologist in the Los Angeles public schools. She has lectured at California State University, Long Beach and California State University, Los Angeles. She was a health occupation specialist with the California Department of Education's Bureau of Industrial Education, and served on the Los Angeles Unified School District Board of Education. President George Bush won the state by 118,457 votes. Without Ohio's electoral votes, the election would have been decided by the U.S. House of Representatives, with each state having one vote in accordance with the Twelfth Amendment to the United States Constitution.

;Opposition to policies of President George W. Bush

Congresswoman Watson supported withdrawal of U.S. troops from Iraq, opposed media consolidation, supported expanding welfare coverage, and opposed President Bush's proposal to privatize Social Security. Watson opposed the Bush tax cuts, saying they were unaffordable.

;Cherokee Nation

On the issue of Cherokee Freedmen citizenship in the Cherokee Nation, Watson noted that 20,000 Cherokee lived in California. She opposed the Cherokee Nation's March 2007 vote to amend its constitution to limit citizenship to only those descendants with at least one Indian ancestor on the Dawes Roll. She noted that when freedmen were granted citizenship in the tribe in 1866 by a treaty which the Cherokee Nation made with the US government, it was without restriction to those freedmen with Indian ancestry. Appeals to the Cherokee Nation's position were pending, in part because the tribe excluded descendants of Cherokee freedmen and intermarried whites from voting on the amendment. In June 2007 Watson introduced a bill to sever US relations with the tribe and revoke its gaming privileges unless the Cherokee Nation restored citizenship in the tribe to descendants of Cherokee freedmen. This drew the ire of several tribal leaders and individuals in Indian Country, accusing her of undermining Native American tribal sovereignty.

;Other issues

Throughout her career in Congress, she advocated for increased funding and research directed at the HIV/AIDS pandemic. She argued in favor of humanitarian assistance for African nations that had been decimated by the disease.
