The party that prides itself on conservation has abdicated its responsibilities in the face of global warming. And the party historically anchored in fiscal restraint has nearly doubled the national debt, squandering our precious resources in an undisciplined and unprecedented effort to finance a war with tax cuts.

America has seldom faced more critical choices: whether we should maintain an occupational force for decades in a country and region that resents western intervention or elect a leader who, in a carefully structured way, will bring our troops home from Iraq as the heroes they are. Whether it is wise to continue to project power largely alone with flickering support around the world or elect a leader who will follow the model of General Eisenhower and this president’s father and lead in concert with allies.

Whether it is prudent to borrow from future generations to pay for today’s reckless fiscal policies or elect a leader who will shore up our budgets and return to a strong dollar. Whether it is preferable to continue the policies that have weakened our position in the world, deepened our debt and widened social divisions or elect a leader who will emulate John F. Kennedy and relight a lamp of fairness at home and reassert an energizing mix of realism and idealism abroad.

The portfolio of challenges passed on to the next president will be as daunting as any since the Great Depression and World War II. This is not a time for politics as usual or for run-of-the-mill politicians. Little is riskier to the national interest than more of the same. America needs new ideas, new energy and a new generation of leadership.
