US presidential hopeful Senator John Kerry continues his winning streak, snatching two more states in his bid for the Democratic nomination. Both Virginia and Tennessee have fallen under the Kerry spell based on the latest vote count. "Americans are voting for change -- East, West, North and now in the South," Kerry said at a victory rally in Fairfax, Virginia. "We will fight for every vote, and we will carry our cause all across this land." The Kerry onslaught has claimed another scalp. Retired General Wesley Clark has reportedly decided to bow out of the race after his poor showing. "We'll leave Tennessee even more full of hope and even more committed to building a better America than when we began this journey five months ago," Clark told supporters in Memphis, Tennessee, less than an hour before pulling out. Kerry's victory has also rattled his other main challenger John Edwards. After all, he hails from the south -- exactly where Kerry has notched up his latest wins. Edwards says however he'll fight on. He immediately flew to Wisconsin to focus on the next test in the nomination race. Kerry's only other serious rival, Howard Dean, once the front-runner but now trailing badly, is also targetting Wisconsin. He has promised to make this his last possible stand against Kerry. With his party's nomination inching closer, Kerry however is already ignoring his Democratic rivals and focussing his energies on George W. Bush.
