Billionaire investor Warren Buffett met Barack Obama back 2004, and he liked what he saw. "I've got a conviction about him that I don't get very often," he told the Chicago Tribune (registration is required to read the story) back in 2005. "He has as much potential as anyone I've seen to have an important impact over his lifetime on the course that America takes." Now Buffett, who's also known for his impact, is lending Obama a helping hand. Last night Buffett introduced Obama to his fellow Nebraskans at a country club in Omaha.

The dinner attracted 200 guests who donated at least $160,000 to the Obama cause, and the campaign promises a bigger event outside Nebraska later this year. Buffett also backs Hillary Clinton; he participated in a Manhattan fundraiser in June that brought in $1 million.
