According to early voting totals, incumbent Donna Campbell leads challengers Mike Novak and Elisa Chan after early voting in the race for the Republican candidate for state Senate District 25.

Campbell has secured 54.6 percent of the vote so far and Novak and Chan took 20.4 percent and 24.9 percent of the vote, respectively, with 2 of 309 precincts reporting, according to the Texas Secretary of State.

Craig Murphy, spokesman for the Chan campaign, said turnout in Bexar County had not been what campaign officials had hoped for.

Campbell, who has secured 23,718 votes so far, won the District 25 seat in 2012, beating longtime incumbent Jeff Wentworth by a nearly 2-to-1 margin.

Campbell Campaign Spokesman John Oliver said Campbell was working the polling sites until the polls closed at 7 p.m.

"[The numbers] look very very positive. We're very excited about them. We feel like our numbers will get stronger [throughout the night]," Oliver said.

During her first term in the Texas Senate, Campbell authored legislation that reduced the number of hours of handgun proficiency coursework one must complete to renew a handgun license.

Campbell also authored legislation requiring investor-owned utilities to paint red any fire hydrants that can produce enough water to adequately fight fires. Black hydrants, which indicate a possibility of inadequate flow and absolve the utility of any liability in the event the hydrant is not able to fight a fire, were an issue in areas of Buda and Kyle.

Black hydrants in both cities were painted red in late summer as a result of the bill.

All election results are unofficial until canvassed.
