Bandit this idea is in fact from the left. John Kerry made the following statement during his 04 campaign;
"We need a new era of service—not an effort for one time, one purpose, or one group—but a permanent and national endeavor. For America now, service is not just an option, but an obligation of citizenship."
[ Kerry, John. "A New Era of National Service." Manchester, New Hampshire. May 19, 2003. (Emphasis mine.)
In the quote above, Kerry didn't put forth a specific government mandate (even if he did elsewhere). Even so, Kerry really was not the ultraliberal everyone claims, so this still doesn't prove your argument.
Oh really? Rangel spends more time criticizing Hugo Chavez than he does Bush.
Also, I thought the point of Rangel's bill was more to discourage the war than anything else. (Of course I agree with him that the war is bad.)
