Armstead serves the district with two other Republicans.
"We believe strongly that we've been effective representatives as a group," he said. "At the same time, we believe as a principle that single-member districts are the best route to go, so we would support adopting those in every district."
Last week, House Majority Leader Brent Boggs, a Braxton County Democrat who chairs the House committee on redistricting, said 100 single-member districts are unlikely.
Much of the debate over multimember districts has focused on the 30th District, where six Democrats and one Republican hold seats.
Many believe Republican candidates would benefit from more single-member districts.
Democrats who hold the seats have said they think the current setup is serving citizens well. Those who back multimember districts also say women are more likely to be represented.
Since early July, the West Virginia Chamber of Commerce has been running radio and TV ads in support of single-member districts, said President Steve Roberts. The group plans to advertise in newspapers, too, as the special session gets closer.
Roberts said the chamber's support of single-member districts is simply a matter of "good government."
He and other proponents of such districts say they would make lawmakers more accountable to constituents and ensure that representatives live close to the voters.
In the 30th District, all members now live in either Charleston or South Charleston.
Running in a race for a single-member district also would be cheaper, he said.
Single-member House districts were the main topic at a Kanawha County public forum on redistricting last month.
Still, Kanawha County Commission President Kent Carper said he hasn't seen "any real great public furor" over single-member districts.
"It's the officeholders, the political insiders, the politicos, the party activists, who generally get angst over this," said Carper, a Democrat.
Carper said it wouldn't bother him if there were more single-member districts but suggested that supporters of such districts are being disingenuous about their motives.
"My argument with the whole bunch is they aren't telling the truth," he said. "None of them will concede one inch that they're doing it for a partisan benefit, that they're doing it to protect their large special interests."
Those who favor the current system also have an obvious political stake in maintaining that setup, he said.
In the end, Carper said, the whole debate comes down to "controlling the legislative process."
