NASHVILLE (AP) - Hendersonville technology consultant Zach Poskevich says he will capitalize on "tea party fervor" in challenging U.S. Sen. Bob Corker in the next year's Republican primary.

Poskevich, an Army veteran making his first bid for office, said in a release announcing his candidacy on Wednesday that he "can do better than Bob Corker."

Corker, a former Chattanooga mayor, had $5.3 million on hand for his re-election bid at the end of the most recent reporting period, compared with $5,000 Poskevich had given his own campaign.

Poskevich acknowledged that he won't be able to challenge Corker's fundraising prowess, which he called "corporate-driven."

Federal Election Commission records list James Patrick Durkan of Chattanooga as another Republican candidate for the seat. No Democrats have joined the race so far.
