What now?

At the end of the day, Hillary Clinton or Barack Obama - or, the real nightmare, both - will be the Democratic Party's nominee. So the question we need to be asking is what we can do to insure that five years from now the Bush tax cuts are gone; our priorities have shifted from military spending to education, housing, jobs, water, alternative energy, transportation, the environment, and so on; we have universal single-payer national health; and we are truly out of Iraq -- no "counter-terrorism" units, no "advisers," no Taj Mahal-sized embassy, no Green Zone, no Halliburton-style contractors and no private security forces. Any ideas?
