Polls closed Tuesday, Nov. 3, across Texas, and voters in the portions of Prosper, Celina and other Collin County communities within Texas House District 66 are waiting to learn whether Republican incumbent Matt Shaheen or Democrat Sandeep Srivastava will represent them in Austin.

The Associated Press, which compiles vote tallies and declares winners in thousands of races nationwide, had not called the District 66 contest as of election night, according to AP's live midterm election coverage. AP reported that official certification of results typically comes weeks later.

In the highest-profile Texas race on the ballot, the AP declared Democrat James Talarico the winner of the U.S. Senate seat at 11:03 p.m. EST, defeating Republican Ken Paxton. Talarico's victory marks the first time a Democrat has won a statewide office in Texas since 1994, according to AP.

The district covers parts of western Collin County, including portions of Plano, Frisco, Prosper, Celina and McKinney, according to Shaheen's Texas House biography.

Collin County's first unofficial results report was expected at approximately 7 p.m. after polls closed, with a second report at approximately 8:30 p.m. and additional updates roughly every 30 minutes, according to the county's Central Counting Station plan. Results are posted on the county elections website.

Matt Shaheen has represented District 66 since 2015, according to BallotReady data. He chairs the House Committee on Elections and serves on the Committee on Higher Education and the Sunset Advisory Commission, according to his Texas House biography. Before joining the Legislature, Shaheen served five years on the Collin County Commissioners Court.

Outside the Capitol, Shaheen is a technology executive. He holds a bachelor's degree from Randolph-Macon College and a master's degree from SMU, according to his House biography.
