Mehlville's Rep. defeated Tuesday night and will face Democrat for the third time in November.
Brown was an incumbent who captured 2,174 or 75.46 percent of the votes. She celebrated with friends and family at an election party at Two Hearts Banquet Center on Lindbergh Boulevard.
"I'm lucky that I'm blessed with a great work ethic, a lot of stamina and a very supportive husband," she said after the victory.
Hotop did not respond to requests for comments.
Looking ahead to the November election
Brown's victory sets up a well-established November rematch with Englund, who won unopposed in the primary.
In 2008, Englund defeated Brown in an election to represent the 85th District, which previously included all or parts of Mehlville, Lemay and Affton, among other sections of South County.
The two candidates faced off again in 2010, when Brown won the election.
Now, two years later, the two candidates will face off in the redrawn 94th District.
"Whatever I am, she's the reverse," Brown said. "I believe I represent the district much better than she does. The district has a lot of conservative people and most of them are pro-life."
Englund, a pro-choice candidate, believes jobs are the most important issue in the race.
"We need to do more incentives for small businesses to hire again; in Jefferson City, we've seen the exact opposite results," Englund said. "I'm not sure that my opponent was able to get much legislation through the jungle that was the legislation this year."
Englund, 38, currently serves as a director on the Lindbergh Board of Education. She holds bachelors and master's degrees in political science from The American University.
Brown, 70, holds a bachelors degree in information systems from Washington University in St. Louis. She previously represented the GOP as a Lemay Republican Committeewoman.
