The latest vote totals show Theresa Daniel is leading Patrick Harden with 200 of the county's 463 vote centers reported.

Daniel currently leads with roughly 67% of votes, as opposed to Harden's close to 33%.

Incumbent Theresa Daniel was elected in 2012 to represent District 1 and is looking at a third four-year term in office if she is successful Nov. 3. District 1 includes parts of Dallas, Mesquite, Garland and Richardson.

Since being elected to the Commissioners Court, Daniel has advocated for improved mental health services, transitional housing for special-needs residents and increased funding for clean air programs. She has a background in public policy and administration and has worked as a U.S. Congressional staff member, according to her online biography.

Daniel’s challenger, Republican Patrick Harden, is a former software trainer, court-appointed mediator, small-business owner and behavior counselor, according to his campaign website. Harden’s campaign focuses on preventing the irresponsible handling of taxpayer dollars as well as combating crime and homelessness.

Some Dallas County voters are also deciding on the District 3 commissioner race, where incumbent John Wiley Price is leading by a wide margin against challengers S.T. Russell and Andrew Jewell.

Ballots are still being counted. These results are unofficial until they are canvassed and certified by the county clerk. Under Texas election law, the clerk accepts and counts mail-in ballots postmarked by Election Day and received by Nov. 4, if they were sent from inside the U.S., or Nov. 9, if they were sent from outside the U.S.
