From Sunlen Miller and Jake Tapper: DUBLIN – “My name is Barack Obama of the Moneygall Obamas. I’ve come home to find the apostrophe that we’ve lost somewhere along the way,” President Obama – or O’Bama as he’s known here– said today from the College Green in Dublin today.
After a visit to his ancestral hometown the president gave a booming and emotional address this afternoon to 25,000 people in downtown Dublin, embracing his Irish roots, including the language.
“Some wise Irish man or woman once said that broken Irish is better than clever English. So here goes.” Obama said first in Irish then repeating in English, ‘I am happy to be in Ireland.’
“We feel very much at home,” the president said joking, “I feel even more at home after that pint that I had. Feel even warmer.”
Mr. Obama thanked the genealogists who traced his roots back to this country which led to his family reunion today in Moneygall.
“It turns out that people take a lot of interest in you when you’re running for president. They look into your past. They check out your place of birth things like that.”
And he even joked that the knowledge about his ancestry would have come in handier when he was a unknown politician in Chicago, the Irish capital of the Midwest, recalling the anecdote that then he could only get the last position possible in the annual Irish Day Parade, just in front of the trash collectors.
“It was a little depressing,” Obama said then of his position in the Irish-American community, “But I’ll bet those parade organizers are watching TV today and feeling kind of bad. But this is a pretty good parade right here.”

The St. Patrick’s Day parade committee really put Barack Obama at the back of the parade?
