Polls indicate more than 60 percent of West Virginians identify themselves as conservatives, which can drive some Democrats away from more liberal aspects of the national party's platform.
Berch also said demographics could be a factor.
"You may lose - in a particular time period - older, more Democratic voters and over time replace them with younger people who are more likely to be independents," he said.
While they may not register with his party, Scarbro said younger independents are good for the Democratic Party.
"Yes, they do register independent, but according to the numbers, they vote Democratic," he said.
Scarbro said the party has targeted these voters.
"We reach out to those people, we encourage our candidates to do so, and that's why we opened our primary in 2008 to allow them to participate," he said.
He also said the rate of growth in independents may actually do more damage to the hold of the state Republican Party.
"Democrats are still the largest segment of (registered voters), and you're seeing independents grow at a faster rate," Scarbro said. "I think you're going to see that trend increase and, by the next two or four years, you'll likely see the number of independents pass the number of Republicans in some counties."
Lucas, of course, disagreed with that prediction.
"Our prediction is that, whatever it boils down to, we're going to see increases in our numbers," he said. "Democrats will see rapid losses in their ranks and independents will grow as well."
He said his primary focus for 2013 is going to be registering new Republican voters, and he plans to do that by targeting disillusioned Democrats and conservative independents.
"We see a lot of this as people switching from Democrat to independent, and now we see it as our job to convince them to join with the party that truly represents the state," Lucas said.
