Wesley Clark: Some whispers in Democratic circles say that should he want it, the offer is there for Clark, a retired four-star general. Given his impeccable military track record (first rank at West Point) and academic background (Rhodes scholarship from Oxford), Clark's a tailor-made US politician, but with little actual experience.
Still, he's the most moderate of the potential candidates, and some see him as leaning a little right, which would appeal to socially conservative blue-collar voters. Plus, he's one of few top-ranking Democrats with military experience, and he polls exceptionally well in the South, where Obama's been blasted outside of the African-American vote.
In 2004, he tossed his hat in the Presidential ring, winning the democratic primary in the traditionally conservative state of Oklahoma, before ultimately endorsing eventual winner John Kerry. It's rumoured that a lack of campaign funds, and little else, really bogged down his campaign. While he's a known Hillary supporter, Clark's career has been driven by his ambition. An offer to be the vice-president might be too difficult to refuse.
