What began as a group on facebook has turned into a grassroots movement. Sam Graham-Felsen wrote on the Obama campaign's official blog, "We have officially passed our goal of one million donors - a remarkable achievement that no one ever thought would be possible.” A counter placed on Sen. Obama's website tracks the number of donors.

The next goal announced via the blogosphere is to make 1 million calls in support of Obama, a number that sounded impossible...before the 2008 Election.

Obama isn't the only one to hit the million mark; Hilary Clinton supporters made an impressive 1.5 million phone calls this month and are planning on making 1.5 million more before the March 4 primaries.

In a statement to their supporters, the Obama campaign wrote, "This is an important milestone, not just for our campaign, but also for our party. This level of support will be invaluable as we head toward a general election in which grassroots participation will be more important than ever."
