Wesley Clark says his departure from the Democratic presidential primaries is "not inevitable." Clark is seeking votes in Tennessee and Virginia in advance of tomorrow`s Democratic primaries. Massachusetts Senator John Kerry is the front runner, with Clark, North Carolina Senator John Edwards and former Vermont Governor Howard Dean all chasing Kerry. Clark, who lives in Little Rock, is trying to show he can win in the South. Polls show Clark trailing in Tennessee and Virginia. He`s also campaigning in Wisconsin in advance of a February 17th primary. The latest distinction Clark was drawing with his rivals is on taxes and toughness. He argues that his background as an Army general makes him the Democrat who can withstand the inevitable brutal assault from Republicans.
