I'd say the sixties played a huge role. It was like a mini-Marxist revolution with the Bolshevik media fueling the fire. There was class warfare, race warfare, gender warfare, drugs, sex, and rock and roll. It fundamentally changed America and America has been going downhill ever since. Now with the explosion of immigrants and minorities, the America we once knew is disappearing. We're turning into another third-world socialist nation. And if Obama wins, he's only going to expedite the inevitable.
Leftists hate everything that has made America great, especially capitalism and our military. They want to destroy it and are succeeding. Sorry,not much optimism here.
