Obama's Speech "His Big Opportunity" BOISE, ID (idaho) - Barack Obama's presidential nomination acceptance speech Thursday night will be a major test for the campaign, according to Linda Wertheimer, National Public Radio anchor at the Democratic National Convention.

"This is [Obama's] introduction. This is his big opportunity. He has to reach people, effect people, reach them emotionally, convince them that he shares their values, and convince them that he is prepared to do something for the country that they want done," Wertheimer said.

"It is a tall order," she added.

Obama will deliver the speech Thursday night at Invesco Field in Denver in front of approximately 75,000 people. © Copyright 2009, idaho
