President Barack Obama's re-election campaign is officially underway after an e-mailed announcement was sent to supporters Monday morning.
A new video on his campaign website also calls on grassroots enthusiasts to once again mobilize.
"We've always known that lasting change wouldn't come quickly or easily. It never does," the Democrat said in the e-mail to supporters announcing his candidacy.

"But as my administration and folks across the country fight to protect the progress we've made - and make more - we also need to begin mobilizing for 2012, long before the time comes for me to begin campaigning in earnest," he continued.
At the moment, the president faces no primary challenger.
More than a dozen Republicans are considering running for their party's nomination. There's no clear front runner in a wide open race.
But Obama, an experienced politician, is taking nothing for granted.
"We're doing this now because the politics we believe in does not start with expensive TV ads or extravaganzas, but with you - with people organizing block-by-block, talking to neighbors, co-workers, and friends. And that kind of campaign takes time to build," he said in the e-mail.
"So even though I'm focused on the job you elected me to do, and the race may not reach full speed for a year or more, the work of laying the foundation for our campaign must start today," Obama added. He directed them to the new red, white and blue website for what he said was "a campaign that's farther-reaching, more focused, and more innovative than anything we've built before."
Now that Obama's candidacy is officially declared and his papers filed, the president will spend more time raising money. Advisers predict he will raise in a record-breaking $1 billion over the next 20 months until the November 2012 election.
