Perhaps a little late to the party, and not unexpected, Al Gore announced his endorsement of Barack Obama. The following email is from just prior to the announcement:

A few hours from now I will step on stage in Detroit, Michigan to announce my
support for Senator Barack Obama. From now through Election Day, I intend to do
whatever I can to make sure he is elected President of the United States.

Over the next four years, we are going to face many difficult challenges --
including bringing our troops home from Iraq, fixing our economy, and solving the
climate crisis. Barack Obama is clearly the candidate best able to solve these
problems and bring change to America.

This moment and this election are too important to let pass without taking action.

That's why I am asking you to join me in showing your support by making a
contribution to this campaign today:

Over the past 18 months, Barack Obama has united a movement. He knows change does
not come from 1600 Pennsylvania Avenue or Capitol Hill. It begins when people stand
up and take action.

With the help of millions of supporters like you, Barack Obama will bring the change
we so desperately need in order to solve our country's most pressing problems.

If you've already contributed to this campaign, I ask that you consider making
another contribution right now. If you haven't, please take the next step and own a

On the issues that matter most, Barack Obama is clearly the right choice to lead our
nation.

We have a lot of work to do in the next few months to elect Barack Obama president,
and it begins by making a contribution to this campaign today.

Thank you for joining me,

Al Gore
