State Senate District 4 Republican incumbent Tommy Williams is the presumptive winner over Libertarian challenger Bob Townsend with 34 of 233 precincts reporting, according to unofficial results.

Williams so far has received 74,639 votes, 85.09 percent of the vote, while Townsend has garnered 13,073 votes, or 14.9 percent.

"It's a very humbling experience and [winning an election] always feels good," Williams said. "I'm also a little overwhelmed by a victory like this."

Williams, who was recently appointed chairman of the senate finance committee, said helping to formulate the state's budget will be among his priorities in the upcoming state legislative session.

"We have also done a lot of work in the past on pill mills and more work needs to be done on that," he said, "and we are drafting legislation that would require people who collect unemployment compensation to pass a drug test."

Williams was elected to the District 4 seat in 2002 and began his first term in 2003. Prior to then, he served state House of Representatives from 1997-2002.

District 4 covers portions of southern Montgomery County, northeast Harris County, all of Jefferson County, except the southern and eastern portions, and all of Liberty County, Chambers County and Orange County.

All results are unofficial until canvassed.
