On Tuesday John Kerry emailed his 3 million person email list to throw his support once again behind four make-it-or-break-it Senate races - Menendez, McCaskill, Webb and Harold Ford, Jr.

The response from the johnkerry.com has been phenomenal - and was the largest turnout on an email to date: the email raised over $300K in just the first 12 hours.

John Kerry asked his colleague Senator Barack Obama, keynote speaker at the 2004 Democratic National convention, to write the "kicker" email to the johnkerry.com community that will be sent to push again for these candidates in these final critical days of the campaign. Kerry enlisted Obama's help in this important team effort -- because our whole party is committed to winning these elections.

Wednesday, Senator Obama sent out an email to the johnkerry.com list.

Below are excerpts from Senator Obama's email:

John Kerry told you yesterday that the control of the Senate comes down to these four states: Tennessee, Missouri, New Jersey, and Virginia. Top Republican strategists have admitted as much.

This is how we will take back the Senate. This is how we will change America. And this is why your donation has never been more critical.

I was honored when John Kerry asked me to keynote his Democratic National Convention in the summer of 2004. In the last two years, he and I have been working tirelessly to win back Congress. And now, it's come down to the final two weeks.

You know the kind of ads we're going to see in these last days. They'll play on our fears, they'll try to divide us, and they'll try to distract us from the real issues in this race - the need for a new course in Iraq, for new leadership in Washington, for a new direction on health care and energy and education.

Americans are tired of being divided, tired of partisan roadblocks, tired of appeals to our worst instincts and greatest fears.

This country is ready for change. This country is desperate for leadership. Now it's up to us to get it done. Let's finish the job.

Let's help America believe again.
