NASHVILLE (AP) - Primary contests for each of Tennessee's three open congressional seats feature at least one candidate spending a hefty amount of their own money in their efforts to secure the Republican nomination.

Memphis physician George Flinn has led the way by pouring $2 million into his bid for the GOP nod to succeed retiring Democratic Rep. John Tanner in the 8th District race in northwest Tennessee.

In the 3rd District, where Republican Rep. Zach Wamp is vacating his seat to run for governor, Chattanooga attorney Chuck Fleischmann has given his bid $598,000.

And former Rutherford County Republican Party Chairwoman Lou Ann Zelenik has given $406,000 to her campaign for the nomination in the 6th District race, where Democratic Rep. Bart Gordon is not seeking re-election.
