This is a nice thoughtful analysis of the basic differences between the Democratics and the Republicans.

For Republicans, American power is rooted largely in military might and showing a tough and resolute face to the world. They would rely on tax cuts as the one and only spur to economic growth.
Obama, Biden and the Democrats, on the other hand, believe that American power depends ultimately on the American economy, and that government has an essential role to play in fostering the next generation of growth.
Notice that when Obama spoke about keeping America in first place, he said not a word about the military. He referred instead to the efforts of our competitors in the public sphere of the economy, and of our past complacency.
"Washington has been telling us to wait for decades, even as the problems have grown worse," Obama said. "Meanwhile, China is not waiting to revamp its economy. Germany is not waiting. India is not waiting. These nations aren't standing still. These nations aren't playing for second place. They're putting more emphasis on math and science. They're rebuilding their infrastructure. They're making serious investments in clean energy because they want those jobs."
Suddenly, Obama's approach is not about old-fashioned Democratic spending. It's about patriotism, competing successfully, investing to maintain American economic leadership. John F. Kennedy provided a slogan for such an effort 50 years ago: "Let's get America moving again."
