Rangle does not really wish to reinstitute the draft. He just wants to shake middle America out of its apathy and horrify them at the prospect of Junior being dragged off to slaughter. Just more insurgency. Besides, the courts were about to strike down the draft as involuntary servitude (Amendment XIII) before it was discontinued. The all-volunteer concept is working.
Rangel voted against his own bill to reinstitute the draft. It was defeated by almost a unanimous vote. The Dems tried to use the threat of the draft, i.e. that Bush was going to reinstitute it, in 2004 in order to get college students out to vote.
Although politically not possible, many Dems would like to see a draft reinstituted, because it gives them more control over the military and younger voters. They have tried to use the Vietnam template to drum up opposition to the Iraq war, but it has not worked. It is difficult to get the public worked up when the people fighting the war are all volunteers. That is why they latch on to a Cindy Sheehan.

Source please. We still have selective service registration and could start up the draft again if this country needed the bodies. I can't see SCOTUS preventing this country from defending itself. The draft has never been declared unconstitutional by any federal court that I am aware of.
