Instead of vague platitudes, Clinton uses empiricism to make his points in last night's speech - America needs to look at what happened over the past 8 years. From last night's speech:

The choice is clear. The Republicans in a few days will nominate a good man who has served our country heroically and who suffered terribly in a Vietnamese prison camp. He loves his country every bit as much as we do. As a senator, he has shown his independence of right-wing orthodoxy on some very important issues.

But on the two great questions of this election -- how to rebuild the American dream and how to restore America's leadership in the world -- he still embraces the extreme philosophy that has defined his party for more than 25 years.

And it is, to be fair to all the Americans who aren't as hard- core Democrats as we, it's a philosophy the American people never actually had a chance to see in action fully until 2001, when the Republicans finally gained control of both the White House and the Congress.

Then we saw what would happen to America if the policies they had talked about for decades actually were implemented. And look what happened.

They took us from record surpluses to an exploding debt; from over 22 million new jobs to just 5 million; from increasing working families' incomes to nearly $7,500 a year to a decline of more than $2,000 a year; from almost 8 million Americans lifted out of poverty to more than 5.5 million driven into poverty; and millions more losing their health insurance.

Now, in spite of all this evidence, their candidate is actually promising more of the same. Think about it: more tax cuts for the wealthiest Americans that will swell the deficit, increase inequality, and weaken the economy; more Band-Aids for health care that will enrich insurance companies, impoverish families, and increase the number of uninsured; more going it alone in the world, instead of building the shared responsibilities and shared opportunities necessary to advance our security and restore our influence.

They actually want us to reward them for the last eight years by giving them four more.

Exactly! Here's the entire speech:
