According to CBS affiliate KHOU-TV, Wilson's direct mail campaign included a flier with smiling black faces he says he found on the Internet. "Please vote for our friend and neighbor Dave Wilson," the accompanying text read.
In another flier, the text said he had been endorsed by Ron Wilson, a popular black former state representative. But the Ron Wilson who endorsed him was Dave's cousin Ron, not the ex-lawmaker.
"He's a nice cousin," Wilson told the network, chuckling. "We played baseball in high school together."
Nevermind his cousin lives in Bloomfield, Iowa, about 940 miles from Houston.
On Tuesday, Wilson defeated Bruce Austin, the 24-year incumbent, by a margin of just 26 votes.
Austin, who is African-American, called Wilson's tactics "disgusting."
"I don't think it's good for both democracy and the whole concept of fair play," he said.
