If asked, DUmmies would simply redefine what Kennedy meant by that. There's nothing they love better than trying to twist the true meaning of words and phrases. They'd say that calling for redistribution of wealth, higher taxes and bigger entitlement programs is dong something for their country, when it's their own shiftless asses they're looking out for. Remember, according to their mantra, when one votes for "their own best interests", that is the most virtuous thing.
Despite all their lip service paid to "helping the downtrodden", I've never seen anything from from 99.99% of DUers that indicates they are about anything more than lining their own dirty little pockets with someone else's money, exercising their sexual perversions consequence-free, unfettered access to drugs, and working out their hateful sense of being losers by punishing everyone more successful in life than them.
