Senator Hillary Clinton's keynote speech spanned her career, campaign and future challenges facing our nation, but from beginning to end she emphasized one key theme: it's time to elect Barack Obama president. And to her supporters who may consider voting republican, she offered the following:

Now, John McCain is my colleague and my friend.

He has served our country with honor and courage.

But we don't need four more years ... of the last eight years.

More economic stagnation ... and less affordable health care.

More high gas prices ... and less alternative energy.

More jobs getting shipped overseas ... and fewer jobs created here.

More skyrocketing debt ... home foreclosures ... and mounting bills that are crushing our middle class families.

More war ... less diplomacy.

More of a government where the privileged come first ... and everyone else comes last.

John McCain says the economy is fundamentally sound. John McCain doesn't think that 47 million people without health insurance is a crisis. John McCain wants to privatize Social Security. And in 2008, he still thinks it's OK when women don't earn equal pay for equal work.

With an agenda like that, it makes sense that George Bush and John McCain will be together next week in the Twin Cities. Because these days they're awfully hard to tell apart.

The audience seemed a little divided at first - some were listening in awe, others were far less interested - but as Clinton's speech picked up momentum the entire audience was captivated.

If Monday night's theme was "values," then Tuesday's was "change." From the posters that read "McCAIN More of The Same" to the (sometimes) rousing speeches from elected officials, the message was clear: America needs a change in leadership to address challenges facing our country. It's time to elect Barack Obama.
