Later in the campaign, Walters and his father, Delegate Ron Walters, R-Kanawha, assailed Martin's negative campaign ad that used photos of Chris Walters when he was a teenager.
One of the photos -- taken from Walters' former MySpace Web page -- showed Walters pointing to a tattoo on a shirtless man's shoulder. The commercial's narrator alleged that Walters had "waffled" on the gay-rights issue.
Walters also criticized Martin for sending out a "robocall" last weekend that called Walters a liar for saying Martin supported raising West Virginia's gas tax. Martin said he never supported raising the fuel tax.
On Monday night, Walters said he would now work hard for residents of the 8th Senate District.
"I was very optimistic getting into the race, and I'm very humbled by the voters in the district," he said.
In another hard-fought Senate race, Republican Mitch Carmichael was leading Democrat Mike Bright in the 4th District late Tuesday night.
With 91 of 104 precincts reporting, Carmichael received 17,717 votes to Bright's 16,722 votes.
The 4th District covers Jackson County, and parts of Putnam, Mason and Roane counties.
Bright is Jackson County's sheriff and a retired State Police trooper. Carmichael is a six-term member of the House of Delegates and an executive with Frontier Communications.
Sen. Corey Palumbo, D-Kanawha, ran unopposed for the 17th District Senate seat. Palumbo serves as chairman of the Senate Judiciary Committee.
