'A More Perfect Union' Barack Obama's defining speech on race could not describe his campaign any better according to Bermudian Spencer Critchley.

Mr. Critchley, an award-winning writer and producer who usually resides in Monterey, California has spent the past two days and will spend the next six months working tirelessly to get the democratic nominee elected.

Having always leaned toward support for Mr. Obama, it was hearing him speak at a Democratic gathering in California a year ago that led to Mr. Critchley's full support for the presidential hopeful.

After hearing the unity speech on March 18 in Philadelphia, Pennsylvania (PA) however, Mr. Critchley packed his bags to volunteer during the final push for the PA Primary on Tuesday.

He said: "Strictly speaking, personally, it was one of the most powerful speeches I have heard in my life. My wife and I sat down and listened to it stream on the internet.

"It was historic and ranked up there with Martin Luther King Jr. and John F. Kennedy. It applies to Bermuda and anywhere there are different communities living together.

"It was insightful and exciting for how he was able to understand the anger and frustration of the black community. I think he's a historic figure. That's one of his values and his campaign is unity.

"We all have to grasp that we all share a common humanity. It's never a solution to a problem thinking there's one group we can blame.

"I think it's one of the reasons why people respond to Barack."

Mr. Critchley, however, does not want to make it sound like Obama has a cult following, but rather a group of supporters who feel invigorated by his message.

"Obviously Barak is doing very, very well. He has every likelihood of winning the election for the nomination and for the presidency.

"But this is not about Barack Obama, he just happens to be the one communicating the message. A good measurement of a leader is if you feel this leader makes you feel powerful then they are a good leader.

"And an oppressive leader makes you feel less powerful. His supporters are made to feel powerful.

"He sees people as people and he understands we are all people. I think that's the key. At the end of the day we want to feel connected and don't want to fight."

It is this message of speaking plainly and dismissing the hype around issues unconnected to his campaign and the presidential election that have also refreshed the American campaign trail.

The democratic nominee hopeful, however, had difficulty sticking to the issues on Wednesday in a debate with Hillary Clinton.

Mr. Critchley said he was 'disturbed' by the lack of issue questions put forward by the press in the first 45 minutes of the debate.

Instead questions circled around incendiary remarks by his former pastor and his reluctance to wear an American flag pin on his lapel.

Many news reports describe Mr. Obama as being on the defensive, tackling questions about his patriotism, understanding of small-town America and his association with the incendiary remarks of his former pastor

But it's his constant sticking to the message and remembering the people who support him, that brings Mr. Obama's supporters back to him.

Mr. Critchley said: "Personally I was really disturbed by the first half-hour to forty minutes and how trivial the questions were. Really it was like high school gossip.

"I think Barack keeps trying to get people back to the topics that matter — health, Iraq and taxes.

"When it got around to the detailed questions about taxes they explained their views and how they thought those issues through. That's the whole concern of the campaign.

""Something (for the US) needs to fundamentally change. So in that sense things are going very well. If I personally had a wish it would be to base the campaign on substance and a little bit less on something emotive.

But even though Mr. Obama is clearly doing well in the polls, as the primary in Pennsylvania looms large on Tuesday, Mr. Critchley and all of Mr. Obama's supporters are working full tilt.

Catching up with him yesterday, the background noise was almost too loud to hear, as Mr. Critchley said he was settled in for a long night.

That's because Tuesday is tipped for Mrs. Clinton's final push to decide if she is going to stay in the race.
