President Bill Clinton was representing his wife, and he swept on stage before 500 enthusiastic supporters who gave him a great welcome.
After his remarks, and as Celtic Woman came on stage, he went backstage with his aides who were urging him to leave for his next event in a crowded evening.
It looked likely he would have come and gone from the concert in a little over a half hour. But no one reckoned on Clinton's affinity for all things Irish.
On his way out he suddenly stopped, turned around and stood in the wings as Celtic Woman started to perform. He seemed utterly caught up in the moment.
Then the group began to wind up for "Danny Boy," and Clinton motioned to everyone backstage to be quiet. The usual hubbub ceased and about 20 or so people stood stock still as the beautiful old air came alive once again.
Unless he is an Oscar-caliber actor, Clinton appeared deeply affected by the song. The stillness backstage added to the intensity of the moment, and when the last note faded away Clinton finally woke, as if form trance, and continued on his schedule.
Except he didn't. Instead he lingered for a further 45 minutes, talking to everyone and anyone backstage, reciting once again his love for all things Irish.
That Irish Vote
BOTH onstage and backstage Clinton continued to pound on the issue of the Irish vote and its importance in upcoming contests. He specifically highlighted Pennsylvania, where according to the U.S. Census, 20% of the electorate is Irish American.
Clinton knows every voting figure like the back of his own hand. He pointed out that 63% of Irish Catholics have so far voted for his wife, which means that they could be in for a very good night when the results start to come in.
Privately Clinton backers believe she will sweep Pennsylvania by close to 15 points, which should set her up for a last minute surge of victories.
