In the latest Gallup Poll, Barack Obama seized his first statistically significant lead -- 8 percentage points -- in surveys by the organization since the controversy arose over sermons by the candidate's longtime pastor, the Rev. Jeremiah Wright. In the poll, Obama has the support of 50 percent of respondents, compared with 42 percent for Hillary Rodham Clinton. It ties Obama's largest lead in this survey since Gallup began nightly polling in early January. The poll was conducted March 25-27 and involved telephone interviews with 1,218 Democratic and Democratic-leaning voters. It had a margin of sampling error of plus or minus 3 percentage points.
