At first glance, Congressman Walter Jones would seem like an improbable target for a conservative primary challenger. Since the seven-term North Carolina Republican arrived in Washington as part of the "Class of '94," he hasn't seen an abortion he wouldn't ban, a tax he wouldn't cut, or an evangelical church he wouldn't free from IRS restrictions against electioneering from the pulpit. Yet Jones has alienated some erstwhile allies in his heavily military district with his passionate and outspoken opposition to the Iraq War.
