PHILADELPHIA, Pennsylvania (CNN) - Sen. Barack Obama, who has mostly avoided focusing on race during his campaign, is delivering a major speech on the issue Tuesday after spending the weekend on the defensive over racially charged statements from his former minister.
The senator from Illinois' biggest challenge is the same as that faced by Republican Mitt Romney, who gave a major speech during his presidential run to reach voters unfamiliar with his Mormon faith: Obama will be looking to explain the Trinity United Church of Christ and its worldview to voters who are aware only of the Rev. Jeremiah Wright's headline-grabbing comments.
And Obama's most pressing task will be his attempt to take control of the campaign narrative after days of tough headlines.
